Wondering if REI would develop their own version of which the English call a “bothy bag” (Karrimor) — basically a small, box tent without a floor, poles. With the new ultra lightweight waterproof fabrics (Araneum) this item would be useful for emergencies, family lunch breaks in bad weather, ski tour breaks. The advantage over a bivy bag it that it shares body heat, heat from breath and some have an opaque panel for light.
