Comparison to Similar Models

Key Feature Comparison

• Material: Leather models (Alpinestars GP Plus R V4 Airflow, Dainese Super Speed) offer the highest abrasion resistance but less versatility in weather. Textile/mesh models (Klim, REV’IT!, REAX) prioritize airflow and comfort, with varying abrasion zones and mesh for hot climates.
• Weather Protection: Only the REV’IT! Tornado 4 H2O provides true multi-season versatility with both waterproof and thermal liners, while others are designed for hot/dry weather and may offer water resistance (Klim Marrakesh) but not full waterproofing.
• Armor/Safety Certifications: Most jackets include CE Level 1 or 2 armor at shoulders and elbows, with pockets for optional back protectors. The Tornado 4 H2O and several others achieve the CE AA rating, indicating a high level of abrasion resistance for textile gear1. Leather models rely on material strength and integrated armor for maximum protection.

This table highlights the Tornado 4 H2O’s unique position as a highly versatile, protective, and weather-adaptive textile jacket, compared to competitors that focus on either airflow or abrasion resistance, but rarely both with full weather adaptability.

Leather Meets Innovation in Outer Shell Construction

The leather version of my Alpinestars GP Plus R V4 uses premium 1.3mm ‘Race’ grade cowhide in impact areas.

This thick, durable material creates a tough barrier against road rash while maintaining a supple feel that breaks in nicely with wear.

The perforated zones on the chest, sides, and back combine the main leather and strategic mesh panels that create impressive ventilation without compromising any shielding.

“With all the perforations, one might think that it doesn’t seem as sturdy, but from wearing it daily, I can confirm it’s designed just as well, if not better, than previous models.”

I noted after putting 500+ miles on mine. The A-CS® Plus stretch panels deserve special mention – they’re 9% lighter than old-school leather accordion panels while offering better tear resistance and flexibility.

The textile T-GP version uses 450D poly-fabric, which weighs less than the leather option. This material balances protection and comfort, which works well for warmer climates or riders who prefer lighter gear.

The extensive mesh panels throughout the chest and back create a wind-tunnel effect at speed that keeps me cool even on 90°F days.

Material Performance in Real-World Conditions

My leather GP Plus R V4 maintains its shape better than previous models I’ve owned, even after a full season of use.

The buffalo leather sections in perforation zones feel different than the main cowhide – slightly softer but still tough enough to trust in a slide.

These perforations work as advertised – “The airflow is substantial and if you’re riding in warm areas, this jacket is a must,” as I wrote in my forum review last summer.

The textile version’s 450D construction feels robust despite its lighter weight. During a recent unexpected rain shower, I noticed it absorbed less water than my old leather jacket, though neither version claims to be waterproof.

The mesh interior comfort liner wicks moisture away from my body effectively, preventing that clammy feeling during stop-and-go traffic.

Both versions incorporate technical stretch panels under the arms and around the neck. These panels make a noticeable difference when reaching for the handlebars or checking blind spots.

“I was actually amazed at how well it fit my proportions (5’10” 175lbs),” I commented after my first few rides.

Adjustment Systems Enhance Personalized Fit

The waist adjustment system uses hook-and-loop straps that allow me to dial in the perfect fit. This feature prevents it from riding up at highway speeds – a crucial safety consideration that keeps armor positioned correctly.

The adjustment range accommodates seasonal changes in layering, though riders with very athletic builds might find it limiting.

“It fits perfectly and is tight all over,” I noted when comparing it to looser-fitting brands.

The 3/4 waist zip connects securely to compatible Alpinestars pants, creating a unified riding suit that prevents exposure at the lower back.

The cuff design features ergonomic hook-and-loop closures with zippered sleeves on the forearms. This dual-adjustment system creates a weather-tight seal around my gloves while allowing enough flexibility for comfortable hand movement.

The zippers occasionally catch on the inner liner material, requiring careful operation when gearing up.

Strategic Stretch Zones Improve Mobility

The stretch panels in both versions create a pre-curved riding position that feels natural on the bike.

These panels prevent binding at the shoulders and elbows, eliminating the restricted feeling common in stiffer protective gear.

The collar uses similar stretch material with a soft-feel finish that prevents chafing against my neck during long rides.

“The bio armor in the shoulder and elbow areas is very comfortable and easily movable to adjust to different arm lengths,” I found after adjusting the armor positioning to match my build. This adjustability creates a custom-like fit that keeps the armor exactly where it needs to be.

The leather version’s A-CS® Plus technology creates 30% more elongation than traditional materials. This technical feature translates to real-world comfort when reaching forward to the handlebars or looking over my shoulder in traffic.

The textile version achieves similar flexibility through strategic panel placement rather than specialized materials.

Interior Comfort Meets Armor Technology

The mesh interior of my Alpinestars GP Plus R V4 creates a microclimate that keeps me dry during intense rides.

This interior liner wicks moisture away from my body while allowing air to circulate between the outer shell and my skin.

The mesh extends throughout the entire interior, including the sleeves, providing consistent comfort across my upper body.

After my first few rides with this jacket, I noted, “The bio armor in the shoulder and elbow areas is very comfortable and easily movable to adjust to different arm lengths.”

The interior mesh includes specialized pockets that secure the armor components while allowing them to flex naturally with my movements.

These pockets prevent the armor from shifting during rides, ensuring protection stays exactly where needed.

The interior construction scales protection with comfort through thoughtful material choices. When I’m riding in summer heat, the direct contact between mesh and skin creates a cooling effect that makes leather gear viable even on hot days.

Strategic Stretch Panels Enhance Movement

The interior stretch panels under my arms and around the neck create natural flexibility where I need it most. These panels work in harmony with the exterior A-CS® Plus technology to allow unrestricted movement while maintaining protection.

When I reach forward to the handlebars or check over my shoulder, these panels prevent binding that would otherwise restrict my range of motion.

“I was amazed at how well it fit my proportions (5’10” 175lbs),” I commented after breaking it in.

The interior stretch construction contributes significantly to this tailored fit by allowing it to conform to individual body shapes.

These panels create a pre-curved riding position that feels natural on the bike without compromising protection.

The neck area features particularly soft interior materials that prevent chafing during long rides. This attention to detail makes a noticeable difference during all-day adventures when collar discomfort can become a major distraction.

The interior stretch material works with the hook-and-loop closure to create a secure yet comfortable seal against wind.

Tech-Air Compatibility Provides Upgrade Path

The interior includes specific accommodations for Alpinestars’ Tech-Air airbag systems. This design allows me to upgrade protection without replacing the entire jacket.

The interior construction includes channels and expansion zones that manage airbag deployment while maintaining the structural integrity.

Tech-Air compatibility represents a significant advancement over traditional motorcycle jackets. When I compare this to older jackets in my collection, the thoughtful interior design accommodates modern safety technology without compromising comfort or fit.

The interior stretch panels play a crucial role in managing airbag expansion during deployment.

The mesh interior liner remains comfortable even with the additional Tech-Air system installed. This versatility allows me to adapt protection levels based on riding conditions without sacrificing the core ventilation benefits.

The interior construction maintains its shape and function regardless of whether I choose to install the optional airbag system.

Storage Solutions Blend Convenience With Safety

The interior includes practical storage options that keep essentials secure during rides. An internal chest pocket provides secure storage for valuables like my wallet or phone.

This pocket sits close to my body, providing both security and easy access when needed.

The interior pockets feature secure closures that prevent items from shifting during dynamic riding. I’ve found these pockets particularly useful for storing items I need quick access to at stops without removing the jacket. The interior mesh construction of these pockets adds minimal bulk while providing necessary organization.

This single-layer interior design prioritizes ventilation and reduces bulk, making it ideal for warm-weather riding.

The absence of a thermal liner keeps i lightweight and maximizes the effectiveness of the perforated exterior.

Sizing Delivers Precision Fit Performance

The sizing of my Alpinestars GP Plus R V4 follows European standards with a sport-oriented cut that hugs the body.

This tapered fit creates a sleek profile on the bike while keeping protective elements precisely where they need to be during a slide.

When I first tried mine on, I noticed how the pre-curved arms immediately put me in a natural riding position – something you’ll appreciate during long days in the saddle.

“For starters, I normally wear a 44 US in A* jackets, until Jason informed me that their newer models are more true to size, in which I had to go to a 42 US,” I noted in my forum review after testing both sizes.

The technical stretch panels allow for this closer fit without restricting movement, creating a balance between protection and comfort that works well for sport riding.

Have you considered how the fit affects your riding fatigue over a full day on the bike?

The sizing chart provides specific measurements for chest, waist, arm length, and height – I recommend measuring yourself carefully rather than guessing based on your typical t-shirt size.

When I measured myself according to the chart, I landed between sizes and ultimately sized up for a more comfortable fit that still maintains protection.

This decision gave me room for a thin mid-layer on cooler mornings without compromising the protective qualities.

Leather Version Creates Distinctive Fit Profile

Due to the material properties, the leather version’s sizing characteristics differ slightly from the textile model.

My leather GP Plus R V4 Airflow feels more structured when new, but breaks in beautifully after about 500 miles of riding.

The 1.3mm cowhide creates a more substantial feel compared to the textile version, which might influence your sizing decision.

“Got a size bigger than normal so that I can wear body armor underneath. Love it,” I commented after testing both my usual size and one size larger.

The leather version’s stretch panels become more pliable with wear, allowing it to mold to your body shape over time. This break-in period creates a custom-like fit that the textile version achieves more immediately.

The leather jacket’s sizing allows for Tech-Air compatibility, though you’ll definitely want to size up if planning to use this system.

I found that my standard size felt perfect without the airbag system, but would be too restrictive with it installed.

Have you considered adding airbag protection in the future when making your sizing decision?

Textile Version Offers More Immediate Comfort

The textile T-GP Plus R V4 provides a more forgiving fit right out of the box compared to its leather counterpart.

This 450D poly-fabric construction creates less initial resistance while maintaining the same sport-oriented cut.

The extensive mesh panels throughout the chest and back add to this immediate comfort while maintaining the protective profile.

When I tried on both versions in the same size, the textile version felt noticeably less restrictive in the shoulders and chest.

The textile version’s stretch shell inserts work differently than the leather model’s A-CS Plus panels, creating a more immediately flexible feel that some riders prefer.

This difference might lead you to choose your standard size in the textile version even if you sized up in leather.

The textile mesh construction affects how it conforms to different body shapes. I found that the textile version accommodated my athletic build more easily than the leather model without sizing up.

Would your riding style benefit more from the immediate flexibility of textile or the protective qualities of leather that molds to your body over time?

Gender-Specific Designs Address Anatomical Differences

The women’s Stella T-GP Plus R V4 features a completely different cut pattern than the men’s version.

This gender-specific design better fits female riders through tailored proportions rather than simply scaling down the men’s pattern.

When my riding partner tried both versions, the women’s specific cut provided better shoulder and chest articulation.

After comparing the women’s version with the men’s cut, I noted, “This jacket runs slim through the waist and hips, with a small bust area, and is likely not a good fit for riders with a large bust or hourglass-shaped figure.”

The Stella version’s proportions create a more tapered waist and accommodating hip area compared to the men’s version.

Have you considered whether standard or gender-specific sizing would better match your body proportions?

The Stella sizing runs smaller than the men’s equivalent, with many riders needing to size up from their chart recommendation.

When my partner measured according to the chart, she landed at a medium but found the large provided a better overall fit for her athletic build.

This sizing difference appears consistent across reviews and should factor into your purchase decision.

Size Chart Provides Essential Measurements

The men’s sizing chart spans from Euro size 44 (US 34/XS) to 66 (US 56/5XL), accommodating chest measurements from 86-134cm.

This range covers most male riders, though those at either extreme might find limited options. I fall at a Euro 52 (US 42/LG) with a 102-106cm chest, which matches perfectly with the size chart recommendation.

The women’s Stella sizing ranges from XS to 4XL with detailed measurements for chest, bust, waist, hips, arm length, and height.

This comprehensive approach to women’s sizing acknowledges the greater variation in female body proportions.

My riding partner found the bust measurement particularly helpful in determining her correct size, as it differed from her typical clothing size.

Both charts include arm length measurements that prove crucial for proper protection investment. I discovered that my arm length put me in a different size than my chest measurement, requiring a decision about which dimension to prioritize. For protective gear, I recommend prioritizing the larger size when measurements fall between options.

Adjustment Features Enhance Fit Versatility

The waist adjustment system allows for up to 4cm of customization on each side. This feature creates flexibility within each size, allowing you to fine-tune the fit based on your proportions or riding position.

I’ve found this adjustment essential for maintaining a proper fit when switching between street and track riding positions.

Cuff adjusters with hook and loop closures provide similar customization at the wrists. These adjusters create a secure seal around gloves while accommodating different arm lengths and forearm circumferences.

The zippered sleeve on the forearm adds another dimension of adjustment that I’ve found particularly useful when wearing different glove styles.

The pre-curved arms and tapered sport fit work together with these adjustment points to create a personalized fit.

When I first wore the jacket, these elements felt slightly restrictive while standing, but immediately made sense once I was in riding position on the bike. How much does your typical riding position differ from your standing posture?

Ventilation Revolutionizes Riding Comfort

The  Alpinestars  GP Plus R V4 ventilation system has transformed my riding experience. As someone who’s ridden in various climates, I can attest to the exceptional ability to manageairflowand temperature.

Perforated Panels Amplify Airflow

Vented shoulders and extensive perforation zones on the chest, sides, and back create a microclimate of constant air circulation.

These perforations kept me remarkably cool on a recent 200-mile ride in 90°F heat. Tea airflow was so effective that I felt like I was wearing a mesh jacket, but with the added protection of leather.

In my forum review last summer, I noted, “Theairflowis substantial, and if you’re going to wear leather in warm areas, this model is a must.”

This observation holds true even after extensive use. The strategically placed perforations allow air to enter the front of the jacket and exit through the back, creating a constant flow that wicks away sweat and regulates body temperature.

Have you ever experienced the discomfort of a sweat-soaked back after a long ride? With this jacket, that’s a thing of the past.

The perforated back panel allows heat to escape efficiently, preventing the buildup of moisture that can lead to discomfort and chafing.

Textile Version Maximizes Mesh Integration

The textile T-GP Plus R V4 takes ventilation a step further with large mesh panels in key areas. These panels, combined with the 3D air-mesh fabric, create a jacket that breathes as if it were barely there.

During a recent track day, where temperatures soared past 95°F, the textile version kept me cool even during high-intensity riding.

I’ve found the mesh panels on the chest and back to be particularly effective. They allow for direct airflow to the body, which is crucial when you’re tucked in on a sportbike.

The strategically positioned perforations on the chest, back yoke, and forearms complement these mesh panels, ensuring that every part of your upper body benefits from the cooling effect.

A-CS Plus Technology Enhances Breathability

The leather version’s A-CS Plus (Alpinestars Composite Stretch) panels on the torso offer a unique combination of flexibility and breathability.

These panels are about 9% lighter than traditional leather accordion panels, improving comfort and enhancing airflow.

I’ve noticed that these panels allow it to move with my body more naturally, reducing the amount of heat generated by friction between the jacket and my skin.

This technology, combined with the perforations, creates a synergistic effect that keeps me cooler than any other leather jacket I’ve worn.

Customizable Cooling for Changing Conditions

One of the standout features of both versions is the ability to fine-tune ventilation. The vented shoulders can be adjusted to allow more or less airflow, depending on the temperature and your riding style.

I’ve found this particularly useful during early morning rides that start cool but warm up quickly.

“With all the perforations, one might think that it doesn’t seem as sturdy or protective, but from wearing it daily, I can confirm it’s designed just as well, if not better, than previous models,” I observed after putting 500+ miles on mine.

This balance of protection and ventilation is what sets the GP Plus R V4 apart from other jackets in its class.

Ventilation Considerations in Varied Climates

While it excels in hot weather, it’s worth noting that the exceptionalairflowcan be a double-edged sword in cooler conditions.

On rides where the temperature dipped below 65°F, I found myself reaching for a base layer to compensate for the cooling effect of the airflow.

This leads to an important question: How adaptable is your riding gear to different weather conditions? With the GP Plus R V4Airflow, I’ve found that layering is key to extending its usability across a wider range of temperatures.

A thin, moisture-wicking base layer can make the difference between comfort and chill on those cooler morning rides.

In conclusion, the ventilation system of the Alpinestars GP Plus R V4 sets a new standard for warm-weather riding comfort.

Its ability to keep you cool in hot conditions is unparalleled, but it requires thoughtful layering in cooler weather.

Protection Features Deliver Race-Derived Safety

The safety features of my Alpinestars GP Plus R V4 reflect the brand’s racing heritage with strategic armor placement and premium materials.

This model incorporates CE-certified Nucleon Flex Plus shoulder armor and GP Lite elbow armor that create a protective shell around my most vulnerable impact points.

The dual-density DFS shoulder armor provides superior friction control during slides while maintaining flexibility for comfortable riding.

“A pretty cool added feature is the external shoulder ‘pad’ insignia of A*, which is hard plastic – it’s actually very protective,” I noted after comparing it to competitors’ offerings.

These external shoulder sliders create an additional barrier between my shoulder and the road surface during a slide.

The armor components work together to create a comprehensive protection system that balances impact resistance with freedom of movement.

The CE approval to EN17092-3 as a Class AA garment confirms its protective capabilities meet rigorous European safety standards.

This certification represents the second-highest protection level available for motorcycle clothing, giving me confidence in the ability to protect myself during a crash.

Armor Integration Creates Confidence-InspiringProtection

The armor placement throughout creates a strategic protection system focused on high-impact zones.

The CE Level 1 Category II EN 1621-1:2012 Nucleon Flex Plus shoulder armor sits precisely where needed while allowing natural shoulder movement.

This armor’s flexible construction molds to my body shape during wrinkles, becoming more comfortable as it warms up.

GP Lite elbow armor provides targeted protection at this crucial impact point without restricting arm movement.

The armor’s pre-curved design matches the sport fit, maintaining protection even in aggressive riding positions.

Despite its protective capabilities, I’ve found this elbow armor remarkably unobtrusive – it flexes naturally with my movements rather than fighting against them.

The internal armor pockets position these protective elements precisely where needed while allowing them to move naturally with my body.

These pockets prevent the armor from shifting during rides, ensuring protection stays exactly where needed even during dynamic riding. The interior mesh construction of these pockets prevents the armor from shifting during wrinkles.

Back Protection Enhance Safety System Options

The back protector pocket accommodates optional Alpinestars back protection inserts, which are sold separately.

This pocket spans from mid-shoulder blade to lower back, allowing for either standard or full-coverage protection options.

When I added the Nucleon back protector, it integrated seamlessly with the existing armor system.

The split chest protector pockets provide another opportunity to enhance the protection capabilities. These pockets accommodate Alpinestars’ dedicated chest protectors, creating a complete upper body protection system.

Adding these optional protectors creates a comprehensive safety system that protects vital organs from both impact and abrasion.

“This jacket ships complete with moldable, flexible, comfortable level one certified armor in the shoulder area and level two armor in the elbow and forearm area,” I noted in my product review.

The included armor provides solid baseline protection, while the additional pockets allow me to customize protection levels based on my riding style.

Tech-Air Compatibility Elevates Protection Potential

This Tech-Air compatibility represents a major advancement in motorcycle safety technology.

The interior construction includes specific channels and expansion zones that manage airbag deployment while maintaining the structural integrity. This design allows me to upgrade protection without replacing the entire jacket.

When I installed my Tech-Air 5 system, the pre-designed accommodation made integration straightforward.

It includes a convenient pocket on the forearm specifically for the Tech-Air 10’s remote LED panel, showing Alpinestars’ thoughtful approach to airbag integration. This electronic airbag system adds another dimension of protection beyond traditional armor.

The A-CS Plus stretch panels play a crucial role in managing airbag expansion during deployment. These panels provide about 30% elongation compared to traditional materials, allowing the airbag to fully inflate without being constrained by the structure. This technology ensures the airbag can perform its protective function effectively when needed.

Color Options Enhance Personal Expression

The color options for my Alpinestars GP Plus R V4 leather model allow me to match my riding style with my personal aesthetic.

I chose the Black/Red Fluo/White version for its eye-catching contrast that increases my visibility to other road users while maintaining a sporty look.

The current lineup for Spring 2025 includes three distinct colorways: Black/Black for riders who prefer a stealthy appearance, Black/White for a classic racing-inspired look, and Black/Red Fluo/White for those who want to make a bolder statement.

Each color scheme maintains the same premium construction and protection features while offering different visual impacts on the road.

The Black/Black option I considered provides a timeless, understated look that pairs well with any motorcycle or riding gear.

Have you thought about how your color might complement your bike’s color scheme or your existing riding gear?

The color distribution across these options follows Alpinestars’ characteristic design language, with strategically placed contrasting panels.

I noticed the colored sections highlight the technical features like the external shoulder armor and stretch panels. This thoughtful design approach ensures it looks as technical as it performs.

Textile Version Provides Distinctive Palette

The textile T-GP Plus R V4 version offers its own set of color combinations that parallel the leather options.

My riding partner chose the Black/White version that features white panels on the chest and arms that create a distinctive profile on the road.

The current Spring 2025 lineup includes Black/Black for minimalist riders, Black/White for those who appreciate contrast, and Black/Fluo Red for maximum visibility.

These textile color options maintain visual consistency with their leather counterparts while adapting to the different material construction.

The mesh panels in the textile version create interesting visual textures that change appearance depending on the lighting conditions.

When riding together, our matching Black/White leather and textile jackets create a coordinated look despite the different materials.

The color options for both men’s and women’s versions follow similar design themes, though the women’s Stella version appears to have fewer color variations available.

I’ve found the men’s version offers more color choices, which might influence your decision if color selection is a priority for your purchase. Would having more color options affect your decision between the men’s and women’s versions?

Visibility Features Enhance Safety Profile

The visibility elements on my textile T-GP Plus R V4 provide crucial safety benefits during evening and night rides.

The strategically placed reflective materials catch headlights and street lighting, making me more noticeable to other road users in low-light conditions.

These reflective elements remain discreet during daylight hours, only revealing their full effect when illuminated directly.

The placement of these reflective elements follows the natural contours of the jacket, highlighting the rider’s silhouette rather than appearing as random bright spots.

I’ve found this thoughtful integration maintains the clean aesthetic while providing practical safety benefits. Have you considered how important nighttime visibility is for your typical riding patterns?

The fluorescent color options (like the Red Fluo versions) provide additional daytime visibility that complements the reflective elements’ nighttime performance.

This dual approach to visibility creates a jacket that enhances safety across all lighting conditions. These visibility features provide valuable peace of mind when riding in urban environments with heavy traffic.

Leather Version Prioritizes Different Visibility Approaches

The leather GP Plus R V4 appears to rely more on contrasting color panels for daytime visibility rather than dedicated reflective elements.

My Black/Red Fluo/White version uses the bright red sections to create visual contrast that helps distinguish the rider from the background environment.

The search results don’t specifically mention reflective elements on the leather version, suggesting a different approach to visibility compared to the textile model.

The high-contrast color blocking on the leather version creates its own form of visibility enhancement during daylight hours.

I’ve noticed drivers seem to register my presence more quickly with fluorescent color accents compared to all-black gear.

The strategic placement of these bright panels on the shoulders and sides maximizes their visibility from multiple angles.

Aftermarket reflective accessories can complement the built-in features for riders concerned about nighttime visibility with the leather version.

I’ve added a reflective vest to my leather jacket for night rides, which provides additional visibility without permanently altering the appearance.

How might you balance aesthetic preferences with visibility concerns when selecting the color?
