More Information

The Men’s Gamma MX Jacket is Arc’teryx’s midweight softshell for mixed conditions on the move—good when the weather can’t decide. It uses Fortius 2.0 fabric for midweight insulation plus wind resistance and water repellent performance, with breathability and exceptional durability you can count on from steep approach to fall hikes.

Articulated patterning and stretch keep movement comfortable, and the regular fit is designed to leave room for light layers. It’s been updated with a PFAS-free FC0 DWR treatment and a roomier regular fit for expanded layering options—exactly the kind of practical refinement you want when the forecast changes after you leave town.
