I purchased these to utilize as a way to transport and store our indoor percussion bands jackets. When we had 30+ kids that we were going to be utilizing jackets for competition season I went on the hunt for a bag that could withstand the abuse of being transported on a bus, thrown on the ground, hold a lot of jackets, store a lot of jackets, and still hold up. These bags did exactly that and still do!We loaded these things with easily 20 jackets and was able to zipper then up, then proceed to unstrap the big backpack straps and carry away. They had to be easily carried on the back while we pushed heavy percussion equipment (marimba, vibe, speakers, synth carts, etc) and not get in the way. These bags held up for an entire season of abuse and are still working great as storage until the next season begins!I highly recommend these!
