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)

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!

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.

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.

Worked great for my 7 year old son over his cast at the pool! No leaks and he wore it for 2 hours. Very durable and easy to put on and take off.

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!

This made my summer dipping into alpine lakes on hiking trips, hanging out with friends at pool parties, AND simply taking showers so much easier while I had a cast on for a broken wrist! Kept out water quite nicely. Only complaint is that 6 months later, it did end up ripping at the arm entrance (I have a DIFFERENT wrist injury that requires a new cast, so am using the glove again), so I am forced to buy a new one. But worked quite well! Definitely a bit pricey though for it solely being composed of rubber. Note: I am not a child but a short (5 ft 3 inches) adult - the large fit my arm well!

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.

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.

Es como un globo gigante, de muy buena calidad, muy resistente, útil y sencillo de usar, mejor que las bolsas de plástico para cubrí un vendaje. No pasa nada de agua, es el mejor!

Wie eigentlich immer bei uns hatten wir Stress: meine Tochter hatte sich den Arm gebrochen, allerdings wollten wir 3 Tage später in den Urlaub fahren. Also Urlaub absagen oder es durchziehen? Wir entschieden uns für letzteres weil meine Tochter unbedingt wollte. Aber was ist ein Sommerurlaub ohne baden im Pool und im Meer? Wir hatten erst überlegt einfach eine Plastiktüte über den Gips zu machen, aber das war uns dann zu unsicher. Wir waren so froh dieses Produkt hier bei Amazon gefunden zu haben und haben es via Prime am nächsten Tag erhalten. Es dauerte nicht lang bis wir den Dreh raus hatten und den Protektor innerhalb kürzester Zeit anbringen konnten. Die Größe passt wie angegeben. Er schneidet am Arm etwas ein, ich denke das ist normal weil er ja dicht halten muss. Wir haben hier in den Rezensionen gelesen dass er nicht sehr langlebig ist, was auch normal ist weil er ja so eng wie möglich bleiben muss. Wir haben also 2 Protektoren bestellt und konnten einen nach dem Urlaub zurückschicken, einer hat für uns wunderbar gereicht. Der Protektor hält absolut bombensicher das Wasser fern und schwimmen macht trotz Gips Spaß. Es ist angegeben, das man nicht länger als 30 Minuten damit baden soll, aber diese Zeit haben wir regelmäßig um ein vielfaches überzogen und trotzdem ist alles gutgegangen. Das Ding hat uns wahrlich den Urlaub gerettet. Sollten wir einmal wieder in diese unglückliche Situation kommen werden wir hier wieder bestellen. Könnte ich 100 Sterne geben würde ich das machen. Super tolles Produkt, klare kaufempfehlung.

Excelente, lo usamos 4 días en alberca y el mar y no entro ni una gota de agua, fácil de poner, sacar el aire con la boca para crear el vacío y quede más apretado, Excelente

Acheté en taille pour un enfant de 7 ans. C'est très pratique pour facilité la douche ou le bain. S'adapte très bien pour un bras dans le plâtre.

Si je pouvais mettre 6 étoiles je le ferai! Ce gant imperméable a sauvé l’été de ma fille de 6 ans! C’est un achat qui fut, de toute évidence, rentable et très utile. Elle pouvait émerger complètement son bras dans l’eau et vivre sa vie comme une sirène. Nous avons été vigilants au début, mais avons osé vers la fin. Sans regret. Le caoutchouc est robuste et de bonne qualité. Grandeur M pour une grande 6 ans qui avait un coude de fracturé.
