The GP Tech v4 is Alpinestars’ new one-piece leather suit, built to a racing specification based on the input of Alpinestars’ most successful riders, to offer race-level technology in a garment optimized for performance, protection and comfort.

Ready for Tech-Air® 10, this suit offers superior freedom of movement and a high level of ventilation thanks to the development of innovative new materials: Ultra-abrasion-resistant and highly breathable MATRYX® zones, Cool-iR Tech treatment to prevent heat build-up and Kevlar® mesh reinforcement to prevent heat transfer.

1. Constructed from advanced materials; MATRYX® structural panels on the thighs, abdomen, chest and back hump provide parametric performance for ventilation and superior mechanical resistance to tearing and abrasion, while being extremely thin and lightweight, with Kevlar® reinforcements to prevent heat transfer.
2. High-performance PU-coated MATRYX® lower leg; directly derived from MotoGP, this innovative lower leg construction offers reduced weight, increased ventilation and exceptional freedom of movement.
3. With a fit designed to offer the highest level of active protection in competition, this suit is already Tech-Air® ready and can accommodate the Tech-Air® 10 Airbag System with its extended hip protection.
4. The GP Tech v4 features a slot on the left forearm to accommodate the wireless LED display of the Tech-Air® 10.5 Airbag System. Cool-iRTecht treatment for optimised body temperature control; this innovative regenerative treatment, integrated into the leather fabric, is a technology that reflects infrared rays from the sun's rays to prevent heat build-up, thus effectively regulating the internal temperature.
