Hyperlite's exclusive new file questions the freedom of a Coast Guard approved jacket. THis new file is the first jacket to have an independent rib panel which sculpts to the shape of a rider's body, dispersing more of the foam on the side, and making a slender design in the chest/stomach region. This extended rib foam area is segmented for more mobility side-to-side. Our thinnest-fitting approved jacket is also our most comfortable. Available with distressed leather outer panels.
