The Bosbag is another great "find". It is practically indestructible, stands open for easy loading and then folds down flat for easy storage. It is made from a heavy duty, tightly woven polyethylene. Mine is going on its eighth year. It's the first thing I grab when I go outside to "hunt and gather" for weeds and spent flowers. It only weighs 10 ounces and has a 3.5 cubic foot capacity.
Dimensions: Open, 22" x 22" x 18"; Folded, 15" x 10" x 1/2"
