Alpine-ready durability and lightweight performance for fast, 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.
