This all black stuff sack is made using the same incredibly tightly woven 100 denier Nylon found in our i-Shadow and i-Explore series Outdoor Education tent floors, providing excellent durability in the long term, with a surprisingly light weight. If you lose, or irreparably damaged the inner tent bag which came with your Wilderness Equipment Outdoor Education tent, this is the solution. This stuff sack fits all WE Outdoor Education tent inners, and outers, and can also be used as a general, heavy duty stuff sack.
