The Youth 180 Trev Pants use our Rider Attack Position™ (RAP) construction for greater comfort while in the 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.
