BLOCCS 100% Waterproof Cast Covers for Shower Arm Kids- Swim Cover, Cast Bag for Bath. Durable Cast Sleeve for Swimming - #CA79-S - Child Arm (Small)

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.

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.

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.

We bought the BLOCCS waterproof cast cover for my 17-year-old daughter before a 10-day overseas vacation that involved daily swimming in pools and the ocean. It worked perfectly the entire time, no rips, no leaks, no stretching out. She was able to be fully submerged in the water every day without a single issue. The most important thing I want people to know: follow the sizing instructions exactly. Don’t assume that teens or adults automatically need an “adult” size. I measured both myself and my daughter, and we both fell under the “Child Large” size. So measure carefully and go by their chart — not by age or body size guesses. Also, putting the cover on and taking it off needs to be done carefully. It’s not something you want to yank over the cast alone. We always had someone help her so the latex didn’t get dragged or torn. That extra caution helped the cover last the entire trip with no damage. Bottom line: if you measure correctly and treat it carefully, this product is worth every penny. Total 5 stars from us.

I wasn’t too sure about this product. The reviews were good, so I figured I would give it a try! My daughter (7) broke her elbow, I thought summer was over for her! We went on vacation and she was able to go into the pool and into the water at the beach! No water got into it at all! Kept her cast dry the whole time! It does fit tight, so you may need 2 people to help put it on, and after maybe wearing it a lot it could possibly stretch out but we only used it for swimming purposes! I am very happy I bought this!

This thing is pretty cool! Keeps my daughter’s arm completely dry so that she can hang in the pool and lake even with an arm in a hard cast all summer. It DOES make her hand sweat. Which make sense, it’s sealing in everything and sealing out water. Also she had one for about 2.5 weeks and it got a tiny hole in it and then just ripped open. Thankfully she wasn’t in the water. I returned it and got another. That was frustrating to deal with not having one for a few days while waiting for the next to come

Went to the beach with our two year old that had a hard cast and there was not a drop of water or sand in it when we left an hour later. She played in the waves and the sand. Also bathed her multiple times with it submerged and the cast never got wet.

Superb product. We had a trip planned to grandma's house in Florida when my 7 year old daughter broke her forearm and received a cast from her wrist to past her elbow. Against doctor's orders, my daughter spent 5 hours a day in the pool for 5 days! No leaks! She had a bit of sweat buildup near her hand, but we just used a hair dryer on the cool setting to dry it afterwards. We obviously did not check it every 30 minutes either, but we did constantly ask her if she felt wetness. The sleeve is very durable, but we still did not let her rough play in the pool because we wanted to avoid any tears. We are still using it now for showers until she gets her cast off. We had a great experience with this sleeve and it saved our pool vacation for our daughter. Highly recommended!
