Arc'teryx  Women's Alpha SL Pant

Sold Out


The women's Alpha SL Pants are lightweight, extremely compatible GORE-TEX® shell pants, designed for hiking and climbing in rapidly changing alpine climates. They're made with waterproof, breathable, and exceptionally light N40r GORE-TEX® fabric with Paclite® technology. Durable ripstop face fabric withstands abrasions, while hardwearing N150p-X GORE-TEX® reinforces critical areas. The regular fit with e3D patterning helps promote freedom of movement and rests comfortably over base layers. Full-length side WaterTight™ zippers make it exceptionally easy to change in-and-out of these pants. Drawcords at the hem along with tuck-away bootlace hooks provide a secure lower-leg fit. Dual low-profile waist adjusters fit comfortably under your daypack. Trim lower legs reduce crampon snags and allow for effective layering.
