Beta AR Pant

Designed for all-around mountain use, the Arc'teryx Women's Beta AR Pants will keep your legs dry during the three hour slog below treeline and will repel snow once you reach the alpine. The waterproof Gore-Tex Pro shell with fully taped seams shed snow, sleet, and heavy rain and will breathe like a champ, so you can enjoy the descent without cold and wet legs.

An athletic fit with e3D technology provides an enhanced range of motion in challenging environments while the adjustable webbing belt keeps the Beta comfortably and securely in place. The 3/4-length WaterTight side zippers help ditch excess heat during the climb and stop below the harness or hip belt area so you won't experience chafing or excess bulk in the backcountry. Arc'teryx also equipped the Beta AR with Keprotec instep patches to protect the pant bottoms against ski or board edges, crampons, and boots while its Cordura PowderCuffs with lace hooks affix the pant to your ski or alpine boots.

What do you think about this product?



Arc'teryx – Women's Beta AR Pant

Made from two different GORE-TEX® Pro textiles, the Beta AR Pant is thoughtfully designed and crafted to balance complete weather protection, light weight, packability and protection from wear and abrasion. The pant is made from N40r-X GORE-TEX® Pro fabric, a lightweight ripstop that delivers waterproof protection, a high level of breathability and surprising durability for its weight. The seat, knees and lower leg are reinforced with burly, abrasion resistant N80p-X GORE-TEX® Pro for added protection in these higher impact areas.


Do these pants have any insulation, or are they just simply a shell pant?

Hey Alaine! These are shell pants and won't have any insulation to make them as light as possible!
