The Boulder Gear Men's Charge Pants are breathable, water- and wind-resistant to stand up to the elements. Zippered thigh vents shed excess heat. The fabric is moisture wicking to keep you dry and cozy on the runs down the mountain. These pants have a full 40g of insulation, and they are critically seam sealed to keep the moisture out. The articulated knee design ensures a full range of motion, and internal boot gaiters to keep the snow out.
