Review: Keeps the Cast Dry! - My kid broke her arm 2 weeks before our beach vacation and her orthopedic doctor recommended this cast cover. It works great! It feels like a thick balloon. My kid said it gets a little sweaty under the cover, but no other complaints. The instructions say to wear for 30 minutes at a time. She comfortably wore it up to 2 hours while playing at the beach. We are going on to week 4 with the cover and not a single leak. It’s been used in the bath, the pool, and the ocean. We used a silver permanent marker to draw scales on it—she calls it her fin. UPDATE: I wanted to update my review now that we’ve finished using the product (and the cast is off!). The cover made it 5 weeks of daily use before it got a pin hole in the upper part that secures the cover to the arm. My daughter’s teacher at summer camp was putting this on her, and I suspect she may have poked the hole with her fingernail. We were able to patch it with flex seal tape to get it through the final sixth week. This is the best cast cover. It’s simple to use, comfortable to wear, and seriously waterproof.
Review: Lifesaver!! - Buy it!! My 7-year-old daughter broke her wrist four days before her pool party, and we were so worried she’d have to miss all the fun. We gave this sleeve a test run the day before—no leaks at all! On party day, she swam for hours and her cast stayed completely dry! The seal is snug (as it should be to keep water out), and while it was a little tight at the top, we just shifted the position each time she wore it to make it more comfortable. It helped to have two people gently stretch the opening while she slid her arm in. It worked like magic and saved one very sad kiddo’s birthday/summer. She’s 7 and the size Medium fit perfectly.

### ⭐⭐⭐⭐⭐ Works as it says!
*by M***R on October 23, 2025*

Have you ever tried to take a shower without getting your arm wet? It's pretty much impossible. This product is described as a waterproof cast cover but, we needed it after surgery on the arm. We could not get the arm wet. This product works great. Good quality and it does just what it is supposed to do. Make sure to order a large enough size since it does fit tight around the arm.
