evo.com | Ripton Bike Pants > The Ripton Bike Pants are purpose-built for pedaling with articulated knees, slim fit, and tapered cuffs that won't catch in your drivetrain. Lightweight cotton blend fabric is thin, strong, and stretchy enough to reduce fatigue on long rides, while an integrated webbing belt fine-tunes the waist fit. Built specifically for the bike, but comfortable enough you might forget to change out of them.
