Liberty Bags Large Drawstring Backpack - Black One Size | Durable Gym & Travel Backpack for Sports, Beach & School | Water-Resistant & Lightweight

Love this as a bag for dance supplies for dance class. I have even taken it to salsa nights to hold my dance shoes, jacket, make-up bag, etc. Large enough for everything and easy to carry on shoulder or used as a backpack. I also take it traveling around the world since it folds up small, is lightweight, but fits a lot of stuff when you need a day pack or overnight pack when you cannot take your entire carry-on to a certain location. My friend even used it on a hike to carry her water, when she forgot her backpack. Will buy again in case this one gets lost or starts looking worn. So far it's holding up very well.
