Arc'teryx Gamma Pant Review

This pair is both comfortable and weather-resistant. The 88/12 nylon/elastane blend makes for stretchy mobility, while the DWR coating and tight fabric weave combine to create a wind and water-resistant award winner. The fabric is noticeably heartier than some other models in this review and resistant to catching on thorns and branches. All in all, we are really pleased with these pants.

Performance Comparison

Comfort and Mobility

The fabric blend on this model is excellent. It includes a higher-than-typical proportion of elastane, which increases their stretch compared to other models. The crotch is gusseted, and the extra fabric creates a modest amount of additional room. The tailoring is nearly perfect, and we feel less resistance to movement in this pair than any other in our review.

The interior of the waist has a soft liner that reduces abrasion. This especially comes in handy if you are carrying a backpack. Considering the weather protection that it provides, this model also finds a way to stay relatively lightweight and flexible.

With its straight-leg fit and articulated knee, the Gamma still allows for solid mobility. One example of the thoughtful comfort features incorporated into these pants is the blunted corner of the snap closure at the waist, which subtly but helpfully eliminates the sharp point in the fabric of many hiking pants that rubs against the stomach. Though they aren't advertised as slim fit, we still think they are a tighter pair of pants geared toward skinnier hikers.

Venting and Breathability

Unfortunately, this may be the weakest metric for these pants. They have a few notable vent points; all of the pockets are medium-gauge mesh. However, the fabric is tightly woven, so their breathability is lacking. During testing, we found that we got hotter faster in this pair than many others in our lineup.

On the plus side, they are relatively lightweight. Their major venting advantage is that they can be rolled up and secured using the elastic cord found in the ankle. Of the models that include this type of feature, the Gamma design is definitely one of the best, meaning we didn't have to pull them up too often.

Weather Resistance

This metric is where the Arc'teryx Gamma differentiate themselves the most from other models. They have a tight fabric weave and an effective DWR coating. They certainly aren't 100% waterproof (if that's what you're after, check out our review of the best rain pants), but during testing, we found ourselves in some consistent light rain that would have been a problem for many other pairs in this review. However, the Gamma held up beautifully. They also beaded water exceptionally well in our controlled spray tests. Eventually, we started to feel wet, but when we were able to check underneath, our skin remained surprisingly dry. Furthermore, because they don't absorb a ton of water, they also dry out fairly quickly.

We are also impressed with their wind resistance, which we attribute to their construction. One unique component of these pants is the eyelets at the ankle. We will admit that we aren't 100% sure how they are meant to be used, but we found that they can turn the pants into a makeshift gaiter somewhat effectively. If you pair these pants with mid- or high-ankle boots, running the laces through the eyelets secures the pants around the top of your footwear. It's not a perfect seal, but in wet weather, it's a nice option.

Features

The features of these pants are minimal but excellent. There are two handwarmer pockets with zippers and an exceptionally wide right thigh pocket with a zipper. We are a little disappointed that there aren't any rear pockets, but it isn't a dealbreaker.

The simple integrated belt makes for a custom fit around the waist, and an adequately sized fly and easy-to-use snap are also included. There's a soft waistband liner, a great ankle cinch cord, and eyelets for gaiter attachments. As for pockets, there are two mesh-lined zippered waist pockets and one zippered thigh pocket. It turns out that the fabric is also more durable than it looks. We got these pants snagged a bunch of times on thorns and rocks, but with no lasting marks to show for it.

Versatility

These pants shine for their versatility. They excel in wet or windy weather, are a comfortable travel option, and look good in both backcountry and frontcountry settings. As mentioned above, we found that they aren't ideal for the heat. We did get sweaty in them pretty quickly in temperatures above 60 degrees Fahrenheit (15 degrees Celsius). However, the roll-up cinch cord built into the ankle does make them serviceable when the mercury rises.

They have a somewhat technical aesthetic but are still meant for everyday outdoor use. Their stretch makes them a good travel option with a comfortable fit and an articulated design. They look good in non-outdoor adventure settings and perform well on the trail, too.

Should You Buy the Arc'teryx Gamma?

The Arc'teryx Gamma offers high performance in high-quality pants. These pants are worth the investment if you are a frequent cool-weather or wet-weather hiker. They are pricey, but we found that when the mercury drops or the skies open up, we are glad to have these pants to protect us. If you generally hike in warmer climates, there are cheaper options that perform better in hot weather. However, if everything else about them says “yes” to you, we don't think you will be disappointed that you spent the money.
