Mammut Men’s Ultimate VIII SO Hooded Jacket

Technical Precision. Built for the Vertical World.

The Mammut Ultimate VIII SO Hooded Jacket is a high-performance softshell engineered for technical climbers and committed alpinists. Drawing on Mammut’s deep heritage of precision mountain craftsmanship, this jacket pushes the boundaries of stretch, breathability, and protection — delivering everything you need for demanding routes and fast-and-light ascents where every gram and every move counts.

Key Features

• Elite-grade softshell (SO) construction for maximum stretch, breathability, and weather resistance
• 4-way stretch fabric engineered for unrestricted movement on technical terrain and rock faces
• Integrated helmet-compatible hood for seamless protection on the wall or ridge
• Precision articulated patterning designed specifically for climbing movement
• Minimal, harness- and pack-compatible pocket placement for clean, unobstructed wear
• Flatlock seams to eliminate chafing and pressure points during extended climbs
• Ultralight and compressible — the performance layer you’ll barely notice until you need it
