Don’t let heavy racewear bog you down. The Thor Prime Pro pants were designed around the notion that light is fast - less weight, less fluff, more speed. Ultra-light thermal-welded panels in the knee and rear yoke enhance durability and coverage. The rib spandex expansion panels and poly spandex blend for the base of the chassis promotes omnidirectional flexibility and allow the rider to move more freely on the bike. Constructed with abrasion resistant materials and large full grain leather inner knee panels, the Prime Pro pants offer class leading durability.
