Durable, waterproof, breathable Gore-Tex Pro 3-layer shell pant for touring, skiing, or snowboarding.

Thanks to the Gore-Tex Pro 3-layer goodness of the Arc'teryx Women's Beta AR Pant, your legs stayed wicked dry and comfortable throughout the three-hour slog through deep snow. The waterproof breathable membrane and fully taped seams shed snow, sleet, and heavy rain, the Pro part means this pant will breathe like a champ so you can enjoy the ski down without wet, cold legs, and the three-layer design holds up to seasons of rough touring abuse.

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 touring boots. A zippered hip pocket holds your lip balm or energy goo.

Good Mobility

Good Mobility

One of our Gearheads tests mobility and articulation in the Beta AR Pant doing a rapid series of 'Mountain Climber' excessive.
WHEW! (Being sprayed down by a garden hose no less).

Hey! They're waterproof!

Great Christmas Gift

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

Got these for Christmas from my mom. Super awesome pants. Very windproof, very waterproof. She got the Raku color and I have to say it is WAY more purple than the picture shows. Makes for an awesome combination since I have the tiger lily (ie ORANGE!) Beta AR and Alpha SV as shell options. the 3/4 (really like 9/10ths) side zips are great because you don't have to worry about overdoing the zipper and can still drop the zipper for extra breathability.

Great pants for winter shell - way too much for a rain pant or something like that.

The built in gaiter is a nice feature and the bottom of the legs is nicely thickened to prevent issues with crampons.

My mom ordered a size up to accommodate baselayering but probably did not need to do this since ArcT designs their shells to fit layers underneath (such foresight so rare in many companies!). I don't mind though since I plan to use them when winter camping and such so a nice pair of insulated pants will easily fit under -- and I like them a little roomy so airflow keeps up - I don't do anything in harnesses currently so I'm not as concerned usually with a tight fit.

All in all - super pants (especially for the 130$ she got them for!) and another killer Christmas gift from my mom.
