Full winter capable, this design has been used in Himalayan climbing and Denali ascents. At 3.75lbs, it is also light enough for summer use, although I think it would be best in cooler places like the high Sierra, high Rockies, or Northeast. Sleeps 3 with plenty of room for gear, or up to five in a pinch.

In excellent condition, used only a few times alas. This should be in the hands of someone who can make use of this extraordinary piece of gear.
