    I am happy when I am warm!

    Okay, so I grew up in southern AZ where snow is minimal and winter is really just more windy and it rains a lot. When I started to venture to the mountains, I found the out really quick how ESSENTIAL it is to have proper gear. I never imagined as a kid that I would be playing in the mountains during a snowstorm, or summiting some of the of the taller peaks in my backyard just for the view. Snow or shine, these pants helped me get there. Yeah they are a bit of a sticker shock $$, but truly, the pockets are big, the warmth is just enough with some incredible breathability and the fit was surprisingly mobile! I did feel that the size 4 were a little short for me at 5'10 but my gaiters helped me out there a little. A must have to stay warm and dry.

    The Gamma MX are AMAZING! Bit expensive, but worth every penny. I wore these as a softshell for skiing. Putting them through plenty of powder, and stayed completely dry! It has a light insulation, so I was able to stay warm. But still breathable so I was never overheating. It fits true to size. Weather you are backcountry skiing, ice climbing, hiking, trekking, these pants will be able to hold up to the challenge! Wish I had them seasons ago, because they really are life changing.

    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.

    Best Pants in the World!

    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.
