The Men's Patagonia R1 Fleece Pant is a lightweight pant for staying warm in cold-weather activities. Polartec Power Grid brings you soft warmth, moisture-wicking, and quick-drying comfort for long days outdoors. Whether it's a bone-chillingly cold hike or snowing and you're ready for skiing and snowboarding, this pant brings the heat. The low bulk allows for easy layering and packing. Equipped with an elastic waistband with drawcord, they'll stay put on the waist, plus, they're just as comfy for bed or fireside in the cabin.
