    Made to Move.

    When you're taking on the challenges of high alpine environments, make sure you're armed with the Arc'teryx Women's Gamma MX Softshell Pant. As the warmest softshell pant in the Arc'teryx Essentials collection, the Gamma is constructed with a midweight fabric that offers wind- and water-resistant protection, while a soft brushed backer adds warmth on cold days. Updated this season with a better women-specific fit, the Gamma MX is designed to give you freedom to move thanks to its stretchy fabric, gusseted crotch, and articulated patterning. Keprotec insteps increase durability by protecting the pant from sharp edges and boots, for season after season of reliable use.

    The Gamma MX is the warmest softshell pant offering from Arc'teryx, and they're absolutely PERFECT for just about everything. They're in their element on alpine climbs, ski mountaineering missions, and anywhere else you might encounter unpredictable weather. They're warm without making you over heat, breathable, and durable enough to protect you from both weather and obstacles that might try to get in your way. These are my go-to pants for ski tours, ice climbs, and long, chilly days in the alpine.

    If you have any questions about Arc'teryx gear, feel free to reach out! I'm their ambassador here in the office, and I'm always happy to chat about anything and everything Arc'teryx.

    I wore these pants day after day while hiking Mt. Elbrus in Russia and these pants kept me cozy warm each day - white outs, heavy snow and freezing conditions. These are the best of the best. I was able to add a pair of compression pants when I felt it necessary and they allow for this. I am 5'6" and 119 lbs. I purchased a size 4 and they are perfect. I have also worn these on trails in CO and Utah for day hikes and they hold up amazingly - even when climbing. I love the protection from my crampons or spikes on the inside of the pant leg. I am in love and know these will be my forever favorite pants for cold conditions.
