Ease of use 4.6 / 5.0

Pros

1. CE AAA Class certification is the highest civilian standard available — and this suit is built to match that certification with materials and technology found nowhere else in production suits
2. MATRYX panels provide superior abrasion resistance, lighter weight, and better ventilation than leather equivalents in the critical contact zones
3. Cool-iR Tech infrared-reflective treatment actively manages heat build-up inside the suit — a direct performance advantage in competitive racing environments

Cons

1. At £1849.99 it’s the most expensive item in the Alpinestars standard range — appropriate for professional and serious competitive racing only
2. The extensive technology requires careful maintenance to preserve the performance of materials like Cool-iR and MATRYX over time
3. AAA Class suit construction is optimised for the racing position — less comfortable in normal upright use off the bike

The GP Tech V4 Leather Suit is Alpinestars’ professional-specification racing suit, built using feedback from the brand’s top athletes and incorporating materials not found in any other production suit. MATRYX ultra-abrasion resistant panels provide parametric performance for ventilation and superior mechanical resistance to tearing and abrasion across the thigh, abdomen, chest, and back hump while being lighter and thinner than leather equivalents. Kangaroo leather in the high-flex zones — arms, hips, and abdomen — combined with race-grade bovine leather forms the primary chassis, and extended Kevlar stretch panelling around the chest, inner arms, crotch, and back leg adds strength and comfort.

The Cool-iR Tech treatment embedded in the leather reflects infrared from the sun’s rays to prevent heat build-up and regulate internal temperature — a racing technology that directly addresses one of the most significant comfort challenges in competitive suit use. Tech-Air 10 Ready with an LED display slot for the Tech-Air 10 wireless display and a Bluetooth display pocket represents the most advanced airbag integration available. GP DFS armor delivers friction control, and internal Race spec GP-R Lite armor provides extended impact coverage. Bio-Flex Race hip armor and replaceable elbow sliders complete the protection system. A detachable short comfort liner with Polygiene treatment and strategic perforations on arms and legs manage ventilation. CE certified to Category II EN17092 AAA Class — the highest civilian certification available.
