Our Verdict
The Arc'teryx Beta is an expensive and well-designed hardshell pant. More than a rain pant, it's clearly designed for general mountain travel, with reinforced cuffs that offer extra protection against crampon points and ski edges, a single harness-compatible pocket, and excellent weather resistance, all at a competitive weight. However, we found that its FC0 DWR treatment wets out quickly, and its alpine climbing-specific features make it too specialized for us to recommend to those looking for an everyday pair of rain pants. However, the Beta would be our top pick for overnight ski tours, alpine climbing, and mountaineering objectives in the lower 48.

Our Analysis and Test Results
The Beta is best-suited for mountaineers and alpinists looking for a pair of lightweight hardshell pants that can accompany them on climbs and ski tours in character-building weather. Their light weight, thoughtful design features centered around mountain travel, and durability ensure that they will seamlessly integrate into a dialed kit for mountain travel.

Water Resistance
The Beta uses an 80-denier, 3-layer GoreTex ePE construction. While the materials used do a great job keeping water out, our testing team found that the face fabric wetted out faster than other pants in the test. While this theoretically has no impact on the Beta's water resistance, it does contribute to a cold and clammy feeling, and takes longer to dry out in a tent or hut. While other pants could simply be shaken out to shed water, and then stored in a pack, the Beta's face fabric holds onto moisture, requiring dedicated time in front of heater, or hanging up inside of a warm tent to fully dry out.

Arc'teryx's product page for the Beta even states that the ePE membrane is known for wetting out faster, but that it doesn't have any bearing on the actual waterproofing. They suggest washing and tumble drying the pants, which can remove oils and help replenish the DWR so it works at its best.
The Beta uses high-quality waterproof zippers throughout the pants, and the single hip pocket is made entirely of Gore-Tex, ensuring that should water make its way into the pocket, you'll still stay dry. The zippers are burly and do an excellent job keeping water out. We also like that they're easy to use while wearing gloves.

Breathability
Three-layer shells aren't known for their breathability, but the Beta is aided by its long, two-way, fully waterproof zippers. While you're unlikely to open the zippers when moving in the rain, they're highly functional for traveling over snow.

Additionally, the C-KNIT backing material helped our testers avoid that classic “plastic bag” feeling associated with strenuous exercise in hardshells.
Comfort and Mobility
The Beta is cut with articulated knees and an articulated seat, and offers ample room throughout to ensure freedom of movement for all mountain activities, even when worn over multiple pairs of pants. Arc'teryx constructed them with so much articulation that they are actually somewhat difficult to put on without partially opening the side zippers.
The Beta's high-mobility cut doesn't come at the expense of bulk; while they certainly aren't a pair of skinny jeans, their fit is slim enough to avoid snagging the inseam on crampons. The C-KNIT backer is comfortable enough to be worn next to skin, which our testers appreciated when shedding or adding layers on the go.

Weight
At 10.7 ounces, the Beta is one of the lighter pants we tested. The reduction in weight doesn't come at the expense of water resistance, functionality, or durability.

They're also light and packable enough to throw in a bag or overnight kit just in case.
Durability
Arc'teryx seems to have made these pants with rugged mountain travel in mind. The 80-denier face fabric is extremely durable, brushing off hard use in abrasive terrain with ease. The Beta performed exceptionally well throughout our testing, punching well above their (literal) weight in our durability testing. Packing this amount of durability into something this light is very impressive.
Additionally, the cuffs are reinforced at notoriously high-impact zones, which is a thoughtful touch that further improves the Beta's already remarkable toughness. While they don't offer the level of protection seen on dedicated ski pants, they handle ski edges and crampon points with ease.

Should You Buy the Arc'tery Beta Pant?
For the average user, the Beta is likely overkill. If you're just bike commuting in the rain occasionally or looking to stay dry on casual hikes, we recommend less burly (and cheaper) options. But if you're looking for an uncompromising and streamlined pair of hardshell pants for technical mountain objectives, the Beta is an excellent choice. Its articulated construction, burly two-way waterproof zippers, and 80-denier face fabric all combine into a very capable alpine hardshell. The reinforced cuffs and harness compatibility differentiate it from other rain pants that we tested. If you know that these features are something that you need, the Beta is a fantastic option.
Although the single pocket isn't equipped with a reversible zipper, you can use it to stash the Beta in a pinch. Because the pocket wasn't designed with this in mind, it doesn't provide much compression, leading to a relatively large packed volume. Credit: Ari Oppenheimer
What Other Rain Pants Should You Consider?
If you don't plan on wearing your rain pants under a harness, there are a number of more compelling options. Our favorite generalist pants are the Patagonia Torrentshell Pant, offering dependable protection in rain and mixed-precip events, for less than half the cost of the Beta. The REI Co-op Rainier Pant is another affordable and decent option. If durability and uncompromising performance in rain are your main criteria, the Outdoor Research Foray 3L is our suggestion, and they'll save you a bit of money over the Beta.
