More Information

Arc’teryx Men’s Gamma MX Pant is built for seasons when weather doesn’t hold a promise. It’s lightly insulated and made to stay breathable and mobile while you’re climbing, touring, or trekking across mixed conditions, long approaches, and winter hikes.

The Fortius 2.0 softshell handles wind and weather, and the gusseted crotch works with the stretch for movement where you need it. Pockets stay accessible whether you’re wearing a pack or a harness. Updates include a PFAS-free FC0 DWR treatment for water resistance, cleaner design lines, and a more comfortable regular fit—so the pant stays dependable without getting in the way.
