Alpinestars GP Tech v2 Jacket For Tech Air Race

Designed and built for performance, the Alpinestars GP Tech V2 Leather Jacket incorporates track proven technology to create a jacket that is aggressive on all fronts. A newly designed speed hump provides ventilation and space for a hydration pack. Bovine leather multi-panel construction resists abrasion and triple stitching helps keep the jacket intact. CE level 1 armor at the elbows and shoulders comes standard. Opt for basic impact protection by adding in optional chest and back armor (sold separately). Or upgrade to the apex predator Tech Air Race Vest. 

Tech Air Race Ready:

This GP Tech v2 Jacket is built to accept the Tech Air Race Airbag System. The vest, which must be purchased separately, installs easily in just a few minutes and does not require any external sensors to operate. Should it detect a crash, it will deploy a protective airbag, providing unrivaled protection to the rider's full back, shoulders, kidney area and chest.
