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.
