ABSTRACT:
A backpacker/mountaineers cot that is lightweight enough to be carried in the backcountry and that is assembled using a minimal of structural cot components in conjunction with various commonly used mountaineer's tools. It allows the elimination of the piece of foam or the inflatable sleeping pad that mountaineers generally backpack. Instead, the mountaineer incorporates his trekking poles, ice ax and internal frame backpack stays with the cot's structural components to form a lightweight, strong or the appropriate assembly of the cot.
