Saved our holiday!
Daughter broke her arm just before our holiday so was advised to purchase one off these and honestly best thing we did, it worked perfectly she spend hours in and out the pool jumping in, water slides and her cast never got wet once! It was easy to take on and off and very well made. You wont regret buying it that for sure.

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 product!
This product is amazing. My son broke his arm and this allowed him to still go in a hot tub when we were away and shower with ease. It’s a little tricky to get on at first as it’s super tight but once it’s on it kept his cast completely dry. I would advise measuring the size of the cast you want to cover to ensure you get the correct size.

Brilliant! Allows swimming to continue!
This product is excellent! No leaks. It has allowed my daughter to continue attending swimming lessons and play in water with her arm in a cast. It fits tight and leaves a mark but it causes no discomfort and is gone in 5 minutes. Brilliant product!

Can get lose at the top and let in water
This is a useful product for a broken full casted arm. It is a bit fiddly to put on but it was kind of expected given it has to be tight at the top. The tightness turned out to be an issue as after a week water did leak inside (yes we did follow instructions I.e. no air inside etc.). But luckily we had bought two sleeves. Why, in case the one got ripped or damaged. We compared the 'old' and the new sleve and the old one had extended at the top tight part buy at least 5 mm! So, we managed and actually use the leaking one inside the extra new one. No more leaks the last week of our hols. It was even luckier the cast did not have to be replaced. Going to hospital on a holiday on a Greek island was not something we would appreciate.

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.

Worth every penny
Saved our holiday. Was very nervous to try this product but it’s exceeded our expectations. Survived the pool, water parks & a swim in lake Garda. Bought two incase one broke but it worked absolutely fine and kept my sons cast dry.

Tier 1 piece of kit 👌🏼
Absolutely brilliant, it saved our family holiday after my son broke his arm. He was able to swim in the sea and the pool and go on all the water rides at the local theme park. It didn’t leak or rip once. Brilliant and can’t recommend it enough. Thank you.

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.

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.
