Holiday saviour
Amazing product, daughter was in tears when the doctor said she wouldnt be able to swim on holiday. However this saved the day! Super strong and waterproof.

Waterproof protecter
This waterproof cover was a lifesaver during my recovery. It fit snugly over my plaster cast and kept it completely dry while showering—no leaks at all. The material is thick and durable, yet flexible enough to slide on and off without hassle. I used it daily and it held up perfectly throughout. It gave me peace of mind and made hygiene so much easier. If you’re dealing with a cast, this is absolutely worth it!

Holiday saviour for a 6 year old
Such a simple but wonderful product which saved our holiday! My 6 year old broke his arm on the last day of term. The only time he cried throughout the whole ordeal was when he thought he wouldn't be able to swim when we went on holiday 2 weeks later. He had a full arm plaster of Paris cast and I purchased the cast protectors as soon as we were discharged home from the hospital. We were initially cautious of just how watertight the sleeve would be but the cast stayed nice and dry during daily baths and showers. Once on holiday we weren't sure how the sleeve would cope with a very energetic 6 year old putting it to the test. However, in no time he was happy and confidently playing in the pool; swimming, snorkelling, jumping around and wrestling with an inflatable crocodile! We took time to read the instructions and made sure the sleeve had a good seal on each occasion. It obviously needs to be a snug fit over the cast, however, it was easy to get on and off with a little bit of practice. Despite taking a couple of spare covers, 2 sleeves lasted the full weeks holiday (and the duration of his cast) with him spending between 6 and 10 hours around the pool each day. As recommended we removed the sleeve for a short period after each hour of use but this provided a perfect chance to get some fluid/ice cream into him and top up the sun cream before he was straight back into the water! I reallyhope this will be the last of the broken bones in our family but this product made living with a cast so much easier. My son is a very slim 6 year old but this product fitted him perfectly. He said it was comfortable and was more than happy to wear it. We have been able to bath and shower him as normal and most importantly, he got to enjoy his holiday he was so looking forward to.

Great idea!
My son was so disappointed at the thought of not being able to swim on a trip away after breaking his thumb but this worked perfectly. Not the easiest to get on and feels a bit tight around the arm but was infinitely better than not swimming!

Brilliant!
My 6 year old broke his arm just before holiday. This was a lifesaver! He used it while in the pool and on the beach with absolutely no problems. No leaks and the cast stayed completely dry. I ordered a medium for him which was perfect. It was easy to get on and off. Without this my son wouldn’t have been able to enjoy his holiday like he did. Definitely recommend 👍

Amazing! Another don’t usually leave reviews post
Daughter (4 years 11 months) broke her arm a week before a UK summer holiday. Reviews were mixed but I thought it was worth a try in order to enjoy swimming pools and beach days. So so glad I did. Really easy to put on. You just fold it back on itself half way. Stretch it open, Ram her arm in and then fold it back. She had it on and off 3 times a day for 1 hour durations in a UK heatwave and no issues at all. No rubbing or moisture no leaking and no discomfort. We did an hour in the sea and playing in sand. Took it off for snacks and ice cream for 40 minutes. Back on again for another hour. We then went back to the caravan park and back on again for swimming in the pool. She was diving under water going on the lazy river (I did put arm bands on due to the weight of the cast). No signs of wear or tear. You take it off like a super tight sock, took about 30 seconds to put on. Size wise I was unsure about small or medium. I went with small which was perfect. Daughter is still just in 4-5 clothes and very average in size for her age but there was still room in the cast cover for another 6 months of growth I think. If you are thinking of buying it just do it and enjoy your holiday!!! Hope this helps. I would recommend to everyone!

Saved my holiday
This Litrally saved our holiday! My daughter broke and dislocated her arm 5 days before we were due to go on our holiday.. we were giving the green light to fly but was concerned about my daughter not being able to enjoy her time away because of her cast and not being able to swim etc.. we found this cast cover and was sceptical about its ability to completely protect the cast from water leakage.. we did a test and it was completely waterproof! She was able to jump in the pool and swim with ease.. if anything being in the water was more comfortable for her as the weight of the temporary cast was more manageable in the water so offered her some relief. The cover itself is easy to use, easy to remove and is really durable. As long as you get the measurements right you’re good to go! The cover allows a lot of space for your hand to move around so you don’t feel restricted. It provides complete protection from water and it came in handy for showering/bathing also. I am so glad I found this and can’t recommend it enough.

Ripped after a week
3 stars, as when it worked it was amazing. However, 1 week into a 2 week holiday the rubber ripped at the top of the arm rendering the entire thing useless. If you’re going to put it on, put it on all day - keep taking on and off and you will probably have the same issue.

Funciona muy bien y resuelve el problema.
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!

Hat uns den Urlaub gerettet
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.

¡Increíble! No entra ni una gota — 100% recomendable
Este protector Bloccs ha sido un auténtico salvavidas. Lo usamos para cubrir un yeso en el brazo de mi hijo durante las vacaciones, y funcionó a la perfección. ¡No entró ni una gota de agua, ni en la ducha ni en la piscina! Es fácil de poner, se ajusta bien sin apretar demasiado y el material es resistente pero flexible. Mi hijo pudo disfrutar del agua como si no llevara el brazo enyesado, y nosotros estuvimos tranquilos todo el tiempo. Sin duda, merece cada euro que cuesta. Lo volvería a comprar sin pensarlo. Producto de 10 si tu peque tiene el brazo escayolado y no quiere perderse el verano.

Lifesaver!
This cast cover is a lifesaver! A nurse recommended it after my daughter broke her arm at the beginning of summer several years ago. This is the 2nd one we've purchased (our kids outgrew the first one we bought). Shower/bathe, swim, etc with no concerns for getting the cast wet. Ordered and delivered same day! I will say getting it on is a 2-person job - think stretching a balloon. Overall though amazing product. I've told many other parents about this product as well!

Saved our vacations
This thing really works (at least with a polymer cast). Keeps cast dry in a pool and on water slides. Saved our vacation.
