Thigh-deep days and frigid temps are no match for the Rab Men's Khroma Volition Pants. These backcountry ski pants offer just the right amount of PrimaLoft synthetic insulation for active warmth, while the burly GORE-TEX waterproof fabric lets you stay dry—and stay out—all day. The 2-layer GORE-TEX material is reinforced with more durable 3-layer GORE-TEX Pro on the lower leg to prevent tears from your crampons or ski edge, while articulated knees and a diamond gusset panel let you kick steps and move through the mountains freely. Other key performance features include zippered thigh vents for temperature regulation, adjustable waistband, plenty of pockets, and elasticated boot gaiters to keep snow out.
