"The Patagonia Insulated Powder Town Pant is built for days that start in a whiteout and end with the last chair. The H2No 2-layer shell and 60g Thermogreen insulation work together to keep legs warm and dry without the bulk that kills mobility on steeper terrain, and the thigh vents give that insulation room to breathe when a long groomer run or skin track pushes the pace. What Our Gearhead® Experts Are Saying:""I trust these through a full storm day because the fully sealed seams and integrated gaiters keep the wet out at every entry point. No cold creep up the ankle when the snow gets deep."""
