Originally made to meet the rigours of ice climbing, the Gamma MX – our warmest Gamma – has evolved to handle a range of mountain activities in mixed conditions.? A wind-resistant, water-repellent stretch softshell, the breathable Fortius 2.0 fabric balances insulation, light weight, and outstanding durability. The StormHood is helmet compatible and protects without impeding peripheral vision, and the articulated regular fit allows room for light layers. What's been updated: Updated with a PFAS-free FC0 DWR (Durable Water Repellent) treatment and a roomier regular fit for expanded layering options.
