    Thrives anywhere on the mountain.

    The Mammut Men's Alyeska GTX Pro 3L Jacket handles bluebird days in the backcountry and snowy days at the resort. Its 3-layer Gore-Tex Pro membrane works with the fully taped seams to provide exceptional waterproofing, and it's proven to ensure higher levels of breathability for the backcountry skiers. Mammut added underarm vents with 2-way zippers for customized airflow, and the removable powder skirt attaches to compatible ski pants for complete coverage. The hood adjusts in three ways for a better fit, and it slides over helmets with ease. The Alyeska also features internal hand gaiters with thumbholes, hook-and-loop cuffs, and multiple backpack-compatible pockets for skins and electronics.

    Breathes Better Than A Mammoth Fur Coat

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: XL

    This thing breathes. I was comfortable no matter what my exertion level was. While hiking to ski I left the jacket on and vented it out with main zips mostly open. Once at the top and in the wind I only had to zip everything up. My only complaint is the pit zips are hard to see and find, but work well once you get a hold of them. The fabric is slightly stretchy and soft which feels nice and is not loud when moving around. Pockets are plentiful. Wrist pocket on left sleeve is great for RFID pass and chapstick. Left chest pocket has a zippered pass through to get to the bib pocket. The main zipper goes to the side of the neck, which allows for more comfort when zipped all the way up. There is another zipper on the neck for a gusset which allows you to get the hood over the helmet without having to unzip the main zipper. Sometimes that zipper sneaks down a little. I really like the zip out powder skirt. The internal mesh pocket holds an iPhone 6S+ with ease. It packs down nicely for a full featured ski jacket. I'm really happy with the jacket.

    I'm 5'10" with a muscular build. 44" chest. The XL gives room to layer without looking too long or baggy like the Trift jacket. This is what Mammut considers a "free ride" fit and is more loose than the other "regular" fit Mammut jackets I have. I appreciate the free ride fit as it allows for layering without restricting range of motion.

    Impenetrable to the elements.....

    • Familiarity: I've put it through the wringer

    Spent this season with the Alyeska Pro jacket and Alyeska Realization pants. I can't say enough about the weatherproofness, durability, and breathability of these garments. The Gore Tex Pro fabric is different from the ArcTeryx Theta AR I was using last season. Much more supple, less annoyingly crinkly, and just as light (I think). The price may seem steep, but with a lifetime warranty, bulletproof construction and a very functional design, I don't regret the investment at all. Compared to the ArcTeryx, Marmot, and Patagonia gear I have used in the past I would say this combo is the best I have used to date, and I will not be switching next season like I usually do.
    Jacket is true to size, but fits slightly loose. I am 5"11" 190 with a muscular build for reference. I would go up a size on the pants. See my review on the Alyeska Realization pants for more details.

    Highly recommended from someone who is rarely happy with outerwear for one reason or another.

    Hey John, I haven't been able to find the Alyeska Jacket in store so i want to order it but I too am usually in between sizes in Mammut. Im 5'11" 180 -185. i wear a 46 inch jacket but have a 30 inch waist. I find that some Mammut styles i am a M and some i am a L. If I wanted to have room to layer would you say a M or L?

    Any insulation?
