Arc'teryx Beta FL Jacket - Men's - $269.97

Once you skin as far as the mountain massive allows, pull the Arc'teryx Beta FL Jacket out of your pack, click into crampons, and begin the long haul to the wind-scoured summit. This lightweight, minimalist shell blocks out the worst of winter when its layered over your down puffy or heavy mid-layer. And despite its pro-level protection (Gore-Tex Active Shell, new for 2011), it doesn't take up a ton of room in your pack. - $269.97
