Arc'teryx Gamma LT Pant - Women's Review

The Arc'teryx Gamma LT pants are made with an 88% Nylon / 12% Elastane blend. This pair comes in size 0-14 in the Regular inseam (32"), as well as 0-10 in Short and 6-12 in Tall inseams. Arc'teryx doesn't specify what length the short and tall inseams are, and we find their limited choices in the different inseams a bit perplexing.

Performance Comparison

The Gamma LT are a sleek pair for colder days or drizzly weather.

Comfort & Mobility

The material blend in this pant is 88% nylon and 12% elastane, which is what makes them so stretchy. The Gamma LT pants have more stretch than comfort to be sure — while they are not uncomfortable, they aren't soft and cozy either. The Gammas are comfortable for all-day wear on the trail — but you probably won't want to curl up in them on the couch afterward.

The cut on these pants is on the trim side, which always concerns us with a pair of hiking pants. We wonder if we are still going to be able to high-step and scramble with ease in "skinny" pants. We needn't have worried about the Gamma LTs. Their material has excellent stretch to it, and the articulated knees and gusseted crotch all combined to give us excellent mobility. We even wore them telemark skiing on a spring day and had no issue going deep into our lunges in this pair.

The articulated knees give the Gammas great mobility for such a trim-fitting pair of pants.

Versatility

It's a little hard to compare this pant's versatility to the others in this review. Okay, it might not work on hot summer days, but it is the only one we tested that we would use on a winter hike, while spring skiing, on wet and cool days, etc. In the end, we gave this one a middle-grade for versatility simply because we can barely even roll them up, and the most common time to go hiking is in the warmer months of the year.

If you are looking for three-season versatility (we're talking summer not winter), then most of the other models in this review are good choices, particularly the ones that convert into shorts because nothing says versatility like being able to remove half the leg.

Need something for spring skiing days? This pair is an excellent choice. There's enough mobility for active sports, and it's slightly thicker than your typical pair of hiking pants.

Durability

This pair earns one of our highest scores for durability.

The softshell material is highly abrasion resistant, and the pant has impeccable construction details. The zippers are laminated, and the seams are all double stitched. We didn't have any durability issues arise during our testing period, and found little to no complaints in online reviews either.

This quality pair of pants should last a long time.

Weather Resistance

Arc'teryx calls this material "moisture resistant." It's not fully waterproof, but it comes close, and on the whole, the Gamma blows away all of the other models in this review for weather resistance.

The Gamma features a DWR finish, and the material and DWR combo does a fantastic job of repelling water. It will keep you dry in a drizzle and takes a pretty sustained rain to soak through - more likely it's the spot where your rainjacket drips onto your pants that will saturate first. Once wet, it takes a bit longer for them to dry compared to some of the "regular" pants that we tested, drying in the full sun in about 40 minutes. The Gammas also provide more wind resistance than most.

The DWR finish on the Gamma works very well - water does not want to go into the material. Once it does get wet, it dries in about 40 minutes in full sun.

Features

We like the feature set on the Gammas. Though they seem pretty minimalistic to start, they do have a lot going for them.

Both hand pockets are nice and deep and have zippers. The side-zippered pocket is big enough for a smartphone or a set of keys. The cuffs have a drawcord should you want to cinch them down to keep the heat in or the rain out. The internal belt is low-profile and doesn't interfere with a hip belt.

The integrated belt is one of our favorite features of this pair. It keeps the pants tight (and UP) and still works decently well under a backpack.

Finally, the cuffs have grommets should you want to wear the pants over a pair of hiking boots and secure them down under the arch with some shoelace, like a gaiter.

The bottom of the pants can cinch down to help keep water or muck out, and there's also a grommet on either side which lets you make your own gaiter out of the pants.

Breathability

For a soft-shell pant, the Gamma LTs are pretty breathable. But their overall weight is a bit heavier than the summer-oriented pants in this review.

If you hike in the Gamma pants in 80-degree weather, they may vent your perspiration well, but you will feel hotter overall than in a super light pair like so many others we tested. The pockets are mesh-lined though, so if you find yourself overheating in these a little, unzip the pockets and try to keep them open a little, as this will allow at least some of your heat to vent out.

This pair breathes well and we feel comfortable hiking in it around 70 degrees, but not much hotter.

Value

These pants ring up at twice as much as some pairs in this review. They are a specialized pair, in a league of their own. It's a lot to spend on one pair of pants, but hopefully they will last you forever!

Skiing one day, hiking the next? The Gamma can do it all!

Conclusion

The Arc'teryx Gamma LT are a sleek pair of hiking pants. Their trim fit and smooth, stretchy material look great on just about anyone, and they are the bee's knees on cold and wet days, making them our Top Pick for Wet Weather. They aren't well suited for warmer weather hiking, but if you're out on the trail no matter the weather or the season, this is a great option to have on you.
