The folks at Household Essentials aren’t kidding when they call their featherweight totes MightyStor.
This polyethylene-tarp zippered storage bag is mighty strong, but it’s also mighty big (22 inches wide by 26 inches high by 12 inches deep) — and that’s just the medium-size model.
The large size (30 inches wide by 26 inches high by 12 inches deep) could carry a collie, not that you would want to.
These rugged bags are tear- and water-resistant and have sewn-in nylon double shoulder straps and a side grab strap. Empty, they fold down practically flat.
