Arc'teryx Gamma LT Softshell Pant - Women's

Pants that deflect wind, shed snow, and breathe—in a featherlight package.

The Arc’teryx Women’s Gamma LT Softshell Pants stand up to tough seasons of ice climbing, high-altitude hikes, backpacking, and guiding—and a lady-friendly fit, comfy stretch, and articulated knees make ‘em feel great the whole time. When Arc’T calls these pantalones ultralight, they’re not joking. Weighing in at just a few hundred grams, these suckers stretch, breathe, and defend you from the elements at very little weight cost. A gusseted crotch lets you mantle the top of an ice pitch, laminated cuffs with cord closures won’t snag on snowshoes or crampons, and thigh pockets with laminated zippers hold your peanut butter cookies.

Great thus far

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Small

I recently bought these pants and really like them thus far. The fit is really comfortable and slim while still allowing for plenty of movement while snowshoing up mtns. I guess I am a little tall (just under 5' 7") but am very happy with the length. If they were any shorter they would be too short for me. Will update review after further use if I find any strong up or downsides.

Great pants but not the perfect pants

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

I bought these pants a few weeks ago for alpine climbing on both rock and ice. The material of the pants are great, they are light weight, and fit is great. However, they are too long and bunch up on the mountaineering boots .. which shouldnt be a problem but its not the slick good fit pant feel either that you would want during technical climbs. Although the material is great for weight and for summer alpine climbs, it is not tough enough to handle alpine rock.. I already have nicks in my pants from sharp rock edges during narrow chimney moves. The leg cinch system is not sufficient to substitute a gaiter when going over snow. I wish they had a lace buckle in the front like some of their hybrid pants for mens or allowed a bungee attachment to go under the boot.
Overall, I would recommend the pants for hiking, but not good for mountaineering or alpine climbing.

great for ski mountaineering

  • Fit: True to size
  • Size Bought: XL

I bought these for a few spring ski mountaineering trips and they were perfect.

They fit great, and can accommodate my wider hip/butt and skier/thunder thighs. They are cut to provide mobility and the stretch in the fabric further helps this. The rise is slightly high for me, but it still worked great (I am also on the short end for wearing an XL). And the wide leg accommodates a ski boot no problem. As others have mentioned, I found them long, and just rolled them up a couple times. If I was really ounce coating I might get them tailored, but I'm not. My ski boots would generally keep the roll in place, but when I was hiking in regular boots I used the drawstring.

The fabric is pretty light, which is great when you're skinning uphill in 70 degree heat or starting your hike close to sea-level in a temperate forest. The hip pockets are mesh lined, so you can further vent the pants by leaving those open.

I noticed that water beaded up and rolled off them pretty easy, (in fact, it seemed an impressive amount of beading for a lightweight fabric that breathes so well) and dirt seems to come clean just as easy in the wash.

For the alpine start, and a cloudy / windy summit, I was able to easily and comfortably wear a merino base layer underneath.

The noise mentioned in a previous review is not something I ever noticed. Perhaps I was just so distracted by the task at hand, or had enough hats/helmets covering my ears, but either way I never noticed it.

Nice pant but too long

    This pant has nice material and nice fit except it is too long. I would expect the length be shorter for XS.

    What is the inseam for xs? Is it 29" as described?

    That's correct-- it'll be a 29 inch inseam for the XS.

    Let me know if you have any other questions-- I'd be glad to help! or 801-736-6399.

    Cinching mechanism

    Very simple to use but effective!

    You can shoelace tie the ends together if they're too long but I haven't found it to be a tripping-type problem like other pants cinching mechanisms.

    Great LIGHT pant

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    These pants are definitely LT and are a little thinner than I perhaps expected but I'm happy about that because it means they'll even work in summer on cooler days at high elevations and such (or perhaps even in warmer days - I'll know more once summer rolls around).

    They stop wind really well, repel water effectively, stretch well providing flexibility of movement, are super comfy, and look good - what more can you really want?

    I ordered the same size as my ArcT rain pants in a moment of stupidity not thinking that I intentionally got those large to fit over other layers so I had to return my first pair. Backcountry was great with the return as always.

    These pants are tighter in the bum and looser in the legs - which provides good flexibility and a look that I like.

    I like the simple cinch cords at the bottom which are much more straightforward than other pants and seem less likely to break than those equipped with button-toggle type systems. There are photos of this cinch on the men's gamma lt page but I'll try to snap a photo to post it here too.

    good pant, one exception

    • Familiarity: I returned this product before using it
    • Fit: True to size

    After reading the reviews this seemed like 'the pant' for everything! Unfortunately, I can't get past how 'loud' it is when moving around at all. It reminds me of the sound of wearing snowpants. Guess I'm pretty sensitive to this, but when I'm out in nature, I want to hear nature, not the constant sound of my crinkly slicky sounding pants. Otherwise, the fit, comfort and sizing was all awesome. But at this price point i need them to be 'perfect' in every way. :-) it just surprised me HOW loud they actually were.....not quite the quietness of a 'soft shell' I expect....

    Over 100 miles

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Hiking the Coast to Coast trail in England through 100 miles of mist, rain, wind and sun, rocky, muddy and moorland trails, these pants have really performed in all weather except long periods of torrential driving rain. Rain pants fit easily over the top. Attractive fit yet pockets roomy enough for map, phone, TP ETC. I am 137 lbs and 5'4". The size 8 fit well with enough room for thin base layer underneath if needed. I wish this pant came in a petite or short. The legs are long for me but if you cinch the bottom cords up tight they make a nice cuff without dragging on the ground. They wash easily and dry super fast. Love these pants!

    Are these pants the right size for the model?

    Definitely recommend

      I was looking for a comfortable (e.g. moves with me) lightweight pant for rock climbing and other mountain activities. These are great. My only constructive input is that the small should not be so long. I'm guessing it's about a 32" inseam. It should be more like 30". The draw strings in the pant legs do a good job and I will be keeping these and am actually considering a second pair.


        I wore them shortly after my purchase to a hiking trip in Shenandoah Park... they preformed amazing.

        breathable-&-warm: Even though it doesn't feel like they breathable when you feel the fabric, they were. Temperatures were constantly changing during our hike, and I always felt comfortable (I am usually very cold when doing nothing, but begin to sweat once my heart rate kicks up)

        I am 5'2 125 pounds- muscularly built with a but, and I got the small and they look and feel really good. the fit is loose enough for being comfortable, but slim and fitted enough to also be flattering.

        I highly recommend these

        What is the accurate inseam measurement...

        What is the accurate inseam measurement for the Arc'teryx Gamma LT Women's Pant in size XL? I need an inseam of at least 35 inches.


        You'd have to go with the tall and they'd be about 34.5" according to ArcT - not sure why you'd need longer though for softshell pants? it's alright if they're a little short since presumably you'd be wearing boots/shoes.

        The tippy-top never felt better than in the fit of Gamma LT Pant; great adjustable belt, stretchy material, and length. TTFN


        For Shizzle!

          This mountaineer lady loves the feel of the nylon, spandex, and fortius for trekking, glasading, or simply meandering up the mountain. Arc'teryx Pants gave me more dexterity while stretching, doing high knees, jumps, and lunges.

          Lightweight, versatile, well-tapered, well-constructed

            I recently purchased this pair of softshell pants for a 1,000-mile-long thru-hike across the Alps from Italy to Monaco this summer. I have been recreating in the Wasatch in advance of my Alps adventure, and I continue to be impressed by the quality of construction (I wouldn't expect anything less from Arc'teryx) and the tapered female fit. Based on previous experience, softshell pants tend to be bulky and uncomfortable in action. The pants kept me toasty warm a few days ago when I woke up to howling winds at 12:30 a.m. in a parking lot on the North Rim of the Grand Canyon to begin a 32-mile, 12-hour-long hiking adventure. I would definitely recommend sizing up a bit so that you can wear something like thermal underwear for added warmth. I am 5'9", 150 pounds, and the size large fits like a perfect glove with tights underneath.
