Great product that is 100% water proof. I had knee replacement surgery and I used it in the shower and later I used it in my pool. I completely submerged my knee and it was bone dry when I got done doing rehab exercises. Highly recommend this for anyone with a cast, wound or sore that they cannot get wet. It fits short legs to super long legs and it is very durable. I bought 2.
Easy to use, and very effective! Would recommend for anyone that has a lower leg cast. Used for my son, the rubber gasket made a tight seal on his thigh, kept all the water out, even during a long shower.
