Designed for riders who relish the opportunity to ride through winter, our warmest pant features Polartec® Alpha® for its great next-to-skin feel and lightning-fast moisture transfer that can match hard aerobic efforts. To keep you warm without excess bulk, the insulation is targeted in panels where it’s needed most, while AmFIB® softshell provides 360-degree breathable protection from wind and cold. Dual zippered trail access pockets hold ride essentials and a PFC-free DWR coating shrugs off moisture. The tapered lower legs are pedal-friendly with zip closures that are compatible with a range of footwear. Wear over your favorite liner and go despite the weather.
