Easy to use and comfortable to wear, the Bloccs waterproof cast cover stretches easily over the cast or dressing to make a watertight seal.

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: Bone Dry Cast!! - Wow, this saved our vacation! My 6-yr old son broke his arm 2 days before leaving for our Mexico spring break. I quickly ordered this for overnight delivery and it worked SO WELL! He did a lot of swimming in the pool, plus snorkeling in the ocean and it kept the cast bone dry. It was a little annoying to get on because it’s so tight and his cast went over his elbow but worth it for my little guy to be able to swim! Highly recommend! He used a size Small and his cast went up past his elbow.

### ⭐⭐⭐⭐⭐ Exactly as described!
*by R***S on March 30, 2026*

Worked perfectly! My 11 year old broke his arm a few weeks before spring break. We had already scheduled a trip to the ocean. This cast cover worked perfectly for our ocean snorkeling trip, swimming in the ocean, swimming in the hotel pool and snorkeling in the stocked saltwater hotel lagoon. My son said the cast cover was comfortable and didn't bother him at all. We used it daily and it never let a drop of water in. Highly recommend!
