Description

Your window to climb – or tour or trek – should not be closed by unpredictable weather, so we designed the Gamma MX Pant to handle whatever comes. Lightly insulated, these breathable, stretchy pants resist wind and weather on mixed routes, extended approaches, and winter hikes. The Fortius 2.0 fabric has a superior warmth-to-weight ratio and is exceptionally durable. A gusseted crotch works with the stretch for freedom of movement, and pockets are accessible while wearing a pack or harness.

What's been updated: Updated with a PFAS-free FC0 DWR (Durable Water Repellent) treatment, cleaner design lines, and a more comfortable regular fit.

Customer service tips: This product is available in three inseam lengths – Short (S), Regular (R), and Tall (T). Please make sure to reference our sizing chart to determine your correct size.
