The Arc'teryx Women's Alpha LT Pants pack mountain-ready protection into a lightweight 15.7oz package thanks to Gore-Tex Pro fabric and a minimalist design. Full-length side zips make it easy to add or subtract layers, and they double as ventilation when temperatures start to rise. Arc'teryx gave the Alpha LT Pants a low-profile elastic waist to make them comfortable under your pack's waist-belt, and removable suspenders help them stay up as you make the last steps to another summit.
Bottom Line: Travel light without sacrificing performance when you pull on the Arc'teryx Alpha LT Pants.
Bought these for my wife, but the butt on these is HUGE! I tried some of the mens on at REI and same thing. There's about 2x's too much fabric back there. Had to return them, you'd need a seriously large booty to fill these things out.
