Looking for a chamois underwear liner for all day use? The Woodchuck has changed the chamois game with its gel insert technology, 3D foam construction, incredibly breathable stretch fabric and silicone bead leg elastic. From huge days of single-track adventures in Fruita or Moab, to epic Gravel Adventures in Kansas, the Woodchuck is a perfect chamois to have in your quiver. At the Sun Valley office, we like it for the all-day adventure of Osberg Ridgeline Trail back to town. Our Design crew developed the ultra-breathable RideTech mesh fabric to be soft and comfy, wicking and quick dry, so go ahead and push it to the limits of physical use. The triple density chamois is male gender specific and the tech gel inserts provide the highest level of comfort in the saddle.
