MontBell Ultralight Down Pant - Men's - $144.95

Round out your winter mountaineering kit with a down jacket and the six-and-a-half ounce Mont-Bell Ultralight Down Pant packed with 800-fill goose down. Montbell used highly-packable insulation and compressible shell material to craft these insulated pants, leaving you little reason to leave them behind when the weather hints at sub-arctic temperatures at night. Rather than carrying heavy fleece pants, or simply going without, treat your legs right, because after all, you're going to need them to get home. - $144.95
