Alpha Jacket Women's is a lightweight shell jacket designed for climbing, built as a light, durable hardshell that provides waterproof-breathable protection for fast, technical alpine ascents in shifting conditions. Product Type: Women’s lightweight shell jacket. Material: GORE-TEX PRO ePE (Waterproof). 50D Hadron™ face fabric for abrasion resistance in rugged terrain. Harness-compatible build with precise articulation for technical movement. Pit zippers for adjustable ventilation during high-output climbing. Pair it with women’s hiking pants and a beanie for variable conditions on technical ascents. The Alpha Jacket is purposefully designed for fast, technical ascents where every gram counts, but having a reliable alpine shield is non-negotiable. Pairing GORE-TEX PRO ePE with 50D Hadron™ face fabric strikes the right balance between waterproof-breathable protection and abrasion resistance, making it ideal for daily use in rugged terrain and shifting conditions. With a harness-compatible build and precise articulation, this jacket is made to climb through any storm. What's been updated: Updated to GORE-TEX PRO ePE, the Alpha Jacket features a new membrane that offers the highest-performing waterproof-breathable protection in an even lighter and more durable package—all while remaining free from intentionally added PFAS. A low-profile RECCO® reflector hidden in the hood brim improves your searchability in emergency situations. A new internal dump pocket makes stashing gloves easy, and the internal security pocket keeps valuables safe.
