    Fast-paced tours to alpine expeditions.

    Loaded with a bevy of smart features and technical fabric details, the Arc'teryx Men's Beta AR Pant protects you from the elements when you're facing down gale-force winds, heavy snow squalls, and freezing temperatures. Featuring Gore-Tex Pro 3-layer membrane/laminate construction, these pants are seriously equipped for the worst weather on the planet. Furthermore, you'll appreciate the pant's athletic fit, with ergonomic-3D patterning for exceptional freedom of movement over base layers.

    Arc'teryx placed a Gore-Tex 3-layer Pro membrane/laminate throughout the entire pant, but with slightly varying face fabrics in strategic locations or what it dubs as "Hybrid Mapping" technology. Basically, you'll find N40r-X Gore-Tex Pro 3-layer body for lightweight, ultra-breathable performance, without sacrificing premium waterproof protection. Reinforced along the seat, knees, and lower legs, N80p-X Gore-Tex Pro 3-layer construction beefs up durability, allowing for worry-free wear in the most grueling environments on earth. Add in fully taped seams and watertight zippers for a near-impenetrable fortress against all-day deluges, sopping spring snow, and deep powder.

    And because these pants are designed for alpine climbing and ski-mountaineering approaches, you'll find an adjustable webbing belt that tightens comfortably under your favorite climbing harness, as well as 3/4-length ventilation zippers for easy integration over crampons. Other key features included Keprotec instep patches for enhanced protection against crampon and boot-related damage, as well as Cordura PowderCuffs with bootlace hooks to seal-out snow and outside moisture.

    Wasted too much time...

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Med / Regular
    • Height: 5'10"
    • Weight: 167lbs

    ...trying to avoid these pants and the pricetag. Now, I don't care!

    I had been deal searching hardshell pants for a couple years just hoping for a good deal on a bombproof goretex multi-use pant. After multiple purchases and returns due to fit issues and performance issues (TNF, Norrona, Marmot) - I finally caved and got these.

    I now can see why they are highly regarded. I can literally Backpack, Bikepack, Bushwack (shroom season approaching), XC Ski, Ski Tour, Snowboard, Portage, etc. The cut, fit, and multiple sizing options are superb.

    Only gripe is the lack of belt loops for a multi-tool, but I'll manage!

    I'm not overweight by any means but I am a stout Midwesterner with thighs and a butt. Something many clothing companies miss on big time, but these pants are sa'weeet...

    Second Pair

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL
    • Height: 6'1"
    • Weight: 220lbs

    My first pair lasted for 10 years, which really surprised me. They held up wash after wash, season after season with no degradation in performance. I got a little larger in the waist over that time, so just picked up the XL version. My teenager is almost big enough to wear my old pair. Worth the price, fit me fine.

    ski pants

    • Familiarity: I returned this product before using it

    I love arcterx product and was really looking forward to these, for the price I expected a better fit. I am 6'4'' 197 lbs 34 waist 34 inseam. Ordered the Large tall and they we too big in waist legs and arse. plus I did not care for the single pocket design nor the crunchy fabric.

    Great pants

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: medium short
    • Height: 5'7"
    • Weight: 160lbs

    Great pants. One of the few goretex pants on the market available in short and long lengths.


    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: L/Reg
    • Height: 6'0"
    • Weight: 170lbs

    I have skied with these pants several times already this season and they are amazing! As comfortable as a pair of jeans and as tough as nails. I have been thinking about purchasing a pair for a while and I am glad I finally did. While the pockets are limited to one on the right hip, all of the other features make up for it. I love the articulated design, as it keep the pants in place. The gaiters have a drawcord that keeps the cuffs synched around my ski boots, and there is a hook that can be unleashed to hook onto boots with laces or a d-ring to keep out the snow. In addition to the overall quality, the fit is perfect. I am 6' and 170lbs and the L/Reg fit great. Not too baggy and not too tight.
    I would expect nothing less from Arcteryx. Do yourself a favor and pick up a pair.

    Are these pants not waterproof and windproof? I dont see that specifically in the tech specs like other pants. Are these better than the Arc'teryx Alpha SL Gore-Tex Pant? Seems like the Alpha should be better, which has full zips and is listed as a guaranteed waterproof and windproof shell. Yet that one is much less expensive. What am I missing?

    Best Answer

    Hey Scott,

    These will be both water and windproof, they're designed to be used in full on winter conditions. The Alpha SL is going to be meant as a much more lightweight hiking/camping waterproof pant option as oppsed to the Beta AR being designed for winter use. The best pant will depend on what you're planning on using them for mostly. Feel free to reach me at my direct line 801.204.4547 or my email if you have any other questions on either of these pants! Best, Connor
