Review: 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 👍

**Q: My son wore this once and it ripped taking it off.  I’m hesitant to order another.  Is this common?**

### ⭐⭐⭐⭐⭐ Holiday saviour for a 6 year old
*by S***Y on 18 August 2015*

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.
