Review: Saved what little bit of sanity I have left🫡 Must have if you’re casted! - In 2025 I had not one of my kids in a cast, BUT TWO 🫠 the first one was a mid arm cast the second one was a full arm cast 🙃 When I tell you these things saved my sanity I am not kidding lol Kiddo #1 was casted 8 weeks during prime summertime. We started off taping trash bags and plastic wrap 👎 learned real quick that wasn’t going to work! So we came across this product, THANK GOODNESS! It works great, kept the cast dry and these kids were in the pool, shower, ocean, alllll the things! Just be very careful putting it on and taking it off! This really is a great product!
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.

### ⭐⭐⭐⭐⭐ Works Exactly as Needed!
*by M***B on January 23, 2026*

The XS size worked great for my 1-year-old during every bath time. Water never got in, and it fits snugly without being too tight. It’s a little tough to put on, but that’s what makes it effective—once it’s on, it does its job perfectly. Definitely recommend it.
