ALPINESTAR MISSILE LEATHER JACKET TECH-AIR*™ COMPATIBLE is a heat seeking sport jacket that that is compatible with the Tech Air 5 Airbag System (sold separately). Premium leather makes up the main chassis with large accordion stretch panels along the torso to help with fit as well as expansion of the airbag. Textile stretch panels on the sleeves keep the jacket fitting snug without feeling constrained. A speed hump is ergonomic at speed and helps to keep your helmet off the ground should you inadvertently end up sliding on your back. Add in chest and back protector inserts for a full suite of impact protection. CE rated elbow and shoulder armor are already included. An inner waterproof wallet pocket keeps its contents dry should get caught in unforeseen rainfall.
