DO NOT BUY THESE. At first they are great and are well thought out. However over time the sides split and then they start to flake. Those little flakes get on and stick to nearly everything they come in contact with. We put them in a backpack for a hike before we caught that they were flaking and we are still picking off little white flakes from items stored in that backpack weeks later. Virtually all the bags seemed to disintegrate at around the same time.
