The most durable GORE-TEX shell is designed for severe (SV) alpine conditions.

Alpha Series: Climbing and alpine-focused systems.
SV: Severe Weather.

The iconic  Alpha SV is a proven performer in severe alpine conditions. Obsession keeps Arcteryx pushing forward, and their close working relationship with Gore, has allowed them to developed the strongest Alpha SV Ever. Utilizing extremely durable yet breathable GORE-TEX PRO with Most Rugged Technology, we have paired our most durable face fabric for incredibly long-lasting storm protection.

The Micro-Grid Backer enhances resistance to abrasion and contamination. The backer is dope dyed, a process using substantially less resources than traditional dye processes. Featured for confidence in extreme conditions, the Alpha SV includes an embedded RECCO® reflector for improved searchability in emergency situations, our helmet-compatible StormHood, pit zips, and articulated construction that frees you to move across mountain terrain.
