The Arc'teryx Kyanite Baselayer Bottoms deliver heavyweight warmth for cold lift rides and high-output winter activities. The brushed polyester interior traps heat against skin while the durable nylon face resists abrasion from boots and outer layers, creating a warm, durable layer that works equally well for skiing, running, or any other cold weather activity you can dream up. Articulated patterning and stretchy construction ensure unrestricted movement, and the zippered thigh pocket holds your phone securely without bouncing around. What are you waiting for?
