Setting a new benchmark in lightweight, warm, packable, synthetic insulated puffy pants, these new Nuclei Pants from Arc'teryx have full length separating side-zippers that make these pants extremely easy to take off and on while wearing things like boots and mountaineering crampons.  Perfect for winter expeditions, bitter cold bivys, and colder weather mountain climbs and adventures of all sorts.  Popular for wearing around camp while snow camping in cold and moist or highly variable changing weather conditions.  A great piece of extreme weather survival gear to have with you when the shit hits the fan.
