Arc'teryx Alpha SL Pullover - Men's - $274.95

The Arc'teryx Men's Alpha SL Pullover epitomizes the light-and-fast ethic. This 11-ounce shell features Gore-Tex Paclite shell fabric for waterproof breathable protection on lightweight backpack trips and alpine rock climbs. The jacket's underarm vent zips let you dump heat when you need to, and one vent zip extends all the way down to the hem for easy-on and -off even when you're wearing a helmet. Fully watertight zippers eliminate leaking. The adjustable storm hood fits over your climbing helmet, and the jacket stows in the front kangaroo pocket when the weather clears. - $274.95
