FOX RACING YOUTH 180 REVN PANTThe Youth 180 Revn Pants use our Rider Attack Position (RAP) construction for greater comfort while in the dirt bike riding position. This articulated fit, combined with TruMotion stretch panels, provides flexibility and more natural movement on the bike. For durability, the pants use a robust 600D polyester construction on the main body. Heat and abrasion leather knee panels on both legs offer further reinforcement in the most critical wear areas.
