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!! Solid waterproof cover, but is tight!
*by M***Q on October 17, 2018*

Definitely MEASURE your child's arm before ordering this product. My son is 11 and I ordered the child's 4-7 size, which fit him perfectly. We had a waterproof cast, but you are still not supposed to submerge them in water for long periods, so I purchased this cast cover for extra protection. This product WORKS VERY WELL if used correctly - we figured out that you had to make sure the rubber was completely extended up the arm and smoothed out at the upper end. Any rolling or crimping at the upper end and the water tight seal may not seal completely. The rubber is TIGHT at the final 2 inches or so on the upper arm - no way around it. I'm sure it has to be this way to create a water tight seal. It takes some getting used to and is not 100% comfortable. My son had to take "breaks" from the product by removing it for 20 minutes or so, then he would put it back on. If you read the package insert, it actually states you should not wear it for more than 60 minutes without taking it off and resting the arm a bit. HOWEVER, with all that being said, this product is a godsend. How anyone could rate this product terribly based on comfort is beyond me. Your child has a cast and you want him or her to play in the water. It is not the ideal situation. But this product allows you to make lemonade out of your lemons. My son broke his arm in gym class TWO DAYS before we were supposed to go on an extended weekend trip to an indoor water park. The trip had been planned for months and involved another family. I was faced with the prospect of him having to sit on the sidelines and watch the other kids have the time of their lives while he sat without being able to participate. Thank goodness for Bloccs and Amazon 2-day prime shipping!! Thanks to this product, my son was able to PLAY at the water park....IN A CAST!!! That is incredible to me. He rode EVERY SLIDE (the glove part of the waterproof cover is sort of like a mitten - I'm not sure if he put his thumb in the thumb part or not but the rubber is soft. My son was able to easily grip the handles of tubes, pool ladders, etc - he had no trouble gripping or using his covered hand), he could SWIM, he could completely SUBMERGE HIS ARM in the pools, he had a BLAST. Was it perfect? No. Would he have preferred not to have had a broken arm for the trip? Absolutely. But that was beyond our control. THANKFULLY, this company had a solution for us. Our vacation was saved. My son had a grin on his face the entire time! As a mom, there is nothing better than that! I would highly recommend this product.
