The 509 Ridge ITB (In The Boot) Pant is purpose-built for riding single track in the mountains. Anatomically fit, reinforced throughout, and styled to complement the rest of your 509 gear—it gives you the complete pro-grade package. Five vented panels prevent overheating while stretch material on the lower legs gives you the freedom to roost without restriction. Rugged construction includes leather reinforced inner leg panels for beefed up protection where it matters most.
