A little bit of water does get in, but it's a tiny amount. I just turn my liner over the top of my leg so the fabric doesn't get wet. I bought two of these just to make sure I'll always have at least one on hand. Using this I can stand up in any shower. I have one of those blue ones that has the bulb that you vacuum seal, but this is way easier and faster to use. I use it every day at the gym. I hang it up when I get home using a pants/shorts hanger so it can dry out. I also use a shower chair once a week to wash the inside of it out with soap and water.
