I've had two Planetwise large wet bags (aqua swirl) and a few smaller ones for over a year now. Aside from slight fading of the cotton due to repeated washing they look brand new. I have another wet bag from a different manufacturer which was much more expensive, yet it has not held up to the dryer at all. The waterproof interior is falling apart. Not Planetwise! In fact, I'm so happy with them I just bought another one.
