I purchased 4 to use as backpacks for a quadriplegic who is in a power chair. I purchase these and when they came in i ordered 4 more so I would be set for several years. He uses 2 bags on the back of his chair; one for his hygiene supplies and the other for straws, napkins, wallet, etc. We purchased the same size backpacks made out of nylon 5 years ago. Those were a great size, but they do NOT compare to these leather bags. These look classy compared the the vinyl bags and the leather will last several years per bag. We are set for 4 years!
