Layer your Haglöfs Men's Barrier Knee Pants under your hardshells and head into the cold. These DWR-treated insulated shorts use synthetic insulation that has a high warmth-to-weight ratio and stays warm even in soggy conditions. The articulated knees and elastic waist move with you to create unrestricted mobility while you're moving through the mountains, and the knee length provides enough coverage to keep your core warm, without the added bulk of fully insulated pants.
