Gamma Lightweight Jacket Mens

The lightest jacket in the Gamma lineup, the Arc'teryx Gamma Lightweight Jacket is an essential softshell outer layer for warmer days and variable conditions on the trail, at the crag, and in the mountains. Fortius™ 1.0 softshell fabric with recycled nylon stretches freely, breathes automatically to release excess heat, and resists wind and light moisture — making it a genuinely versatile piece that maximises time outside across a wide range of activities. UPF 50+ protection, articulated patterning, and a regular fit with room for light layers complete a clean, capable softshell.
