Product details

When the mountain shows its teeth, this is the shell you want. The Alpha SV Jacket is built to endure relentlessly severe conditions, committing ascents, and sustained exposure in the world’s harshest alpine terrain. Constructed with burly 100D GORE-TEX PRO ePE, this shell delivers unwavering waterproof-breathable performance and confidence-inspiring protection that will keep you climbing—even when the mountain is at its worst.

What’s been updated: The Alpha SV has been updated to 100D GORE-TEX PRO ePE, our most durable, waterproof-breathable protection, now even lighter and stronger than before—all while remaining free from intentionally added PFAS. A low-profile RECCO® reflector hidden in the hood brim improves your searchability in emergency situations. Internal storage options have expanded to include two new dump pockets for stashing gloves or a toque, as well as a security pocket to keep valuables safe.
