The super lightweight and packable Arc'teryx Women's Beta SL Pants are easy to stuff in your backpack and have ready at hand if you get stuck out in a deluge or snowstorm. The pants' Gore Tex fabric offers highly breathable and fully waterproof protection at a very light weight. Arc'teryx's rugged N150p X Gore Tex nylon fabric provides reinforcement at the lower leg and hem so the waterproofing isn't compromised by run ins with sharp brush or crampons. The 14 length WaterTight zipper at the hem also keeps water out while making it easier for you to pull the pants over your hiking boots. Once the pants are on, the elastic waist holds the pants comfortably in place. Snug down the waist and hem with adjustment drawcords, and attach the cuffs to your boot laces with the integrated hooks for an extra secure, protective fit. Once you start moving again, you'll love how the anatomic construction allows the pants to follow your movements without restriction so you can get to your destination quickly and more comfortably.
