Easy construction with a very strong rubberized canvas skin. This container is pretty large and can hold a patio umbrella with the poles separated, six lounge chair cushions, two recliner cushions, large ice chest, 100' water hose, two twenty propane tanks, and bunch of other things I have forgotten I put in there. Rugged and water resistant with vent flaps and a plug to run an electrical cord or gas line through. Velcro closures are the only struggle to get a good alignment on.
