Life saver if you want to shower without hassle After surgery. My husband had carpal tunnel surgery and it was painful wrapping his hand and arm in plastic wrap every single time. We bought this sleeve and worked like a charm. He is a big guy and i was concerned that his arm would not fit or opening was too tight but no. He put the sleeve on his own and has plenty of room to move his hand around and the opening fit tight enough preventing water from soaking the bandages. I highly recommend this product
