The Arc'teryx Gamma MX Jacket is a warm, highly durable softshell built for mixed conditions and alpine travel. Its Fortius 2.0 fabric delivers midweight insulation while resisting wind, repelling water and breathing well, with articulated patterning and stretch for freedom of movement.
The regular fit leaves room for light layers, and the updated PFAS-free FC0 DWR treatment keeps the weather out without compromising breathability. Two zippered chest pockets and two zippered hand pockets provide secure storage for essentials on the move.
