Ultra-Light Hiking Pant.

The women's ALPHA SL are Gore-Tex shell pants designed for hiking and climbing in changing alpine climates. Waterproof, breathable, and exceptionally light, the Alpha SL is reinforced in critical areas. Articulated patterning increases your range of movement. The pant rests comfortably over base layers. Low-profile waist adjusters fit under your daypack. Trim lower legs reduce crampon snags and allow for effective layering.
