Went on a backpack hunt in Colorado for elk in October. Morning temps in single digits. cooking gear left out side because of bears. would put boiling water in it for my tea in morning and night and stayed very warm for a long time in these conditions.
My buddys were impressed. Next time I get to a REI I told them I will buy them each one, well worth it.
