The Patagonia Men's R1 Hoody is a fleece pullover for adventures in the alpine. Climbing or skiing, staying warm is all about the layers and this handy midlayer Uses Polartec Power Grid fabric to drop the weight, increase the breathability and above all, keep you toasty. The exterior is smooth so pulling something extra over top is super silky. The front zipper won't completely separate the front but it falls so deep you'll be able to vent quickly and efficiently when your exertion up the mountain gets to be too hot. A hood for your head, thumbloops for your hands, and a chest pocket to keep a pic of your loved one in. Or lipbalm.
