Amazing product! Highly recommend
This worked perfectly for us! My son is 4 and I got an x small. It goes about 2 inches above his elbow and his cast is below his elbow. He was army crawling in the sand, fully swimming in the ocean, and getting as covered in sand as possible. Not one piece of sand was in it and it was completely dry every time! Very easy to use and does the job! Highly recommend this product!

Works Exactly as Needed!
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.

It works for the pool!
I bought the BLOCCS XS a couple of weeks ago for my 5-year-old, who currently has a cast that goes halfway up his calf. The cover fits just below his knee and has been excellent for pool time—his cast has stayed completely dry every single time. For extra peace of mind, I also use a second cast cover, which is a different brand and shape. I found out however, that it’s not pool-proof. That said, the BLOCCS cover does the job on its own—I just use the secondary one as a backup in case of a puncture or rogue cannonball. Bottom line: BLOCCS works great, even with a very active 5-year-old. Highly recommend if you want to keep casts dry without turning pool time into a science experiment.

Works
I bought this for my grandson after he broke his leg, a second time. It is a total lifesaver! It does exactly what it says it will! Pricey, but worth the price!

Saved Swim Practice!
We tried two other "water proof" cast covers before ordering this one. The others would have been fine for a quick shower, but let in a lot of water when any substantial amount of water touched the seal. My daughter wasn't even able to swim with two kickboards, trying to prop her arm as much out of the water as possible, without her cast getting very wet with the other covers. The Bloccs water proof cover is completely different. My daughter has been able to complete two entire 1.5 hr club swim team practices since we received this a few days ago (sticking mostly to kickboard practice) without her cast getting wet, other than condensation/sweat inside of the cover. It's tight, so got a little uncomfortable at first and she took a break mid way to air her arm/cast out, but she didn't have to worry about keeping her arm fully out of the water because it stayed dry even when completely submerged. She's even gone to the bottom of our home pool to retrieve items dropped in and not had any leakage. This is a great cover. Flexible, actually waterproof for swimming, and reusable. It feels similar to the material used in swim caps. I am ordering a second one just in case we rip this one in the month between now and when she gets her cast off. Great for swimming!! Great for showers and baths. She can actually dive underwater with this without water leaking in. Amazing product! Thanks, Bloccs, for saving us from missing out on six weeks of practice before a big swim meet!!

This thing WORKS!!
We purchased multiple different “water proof” options. This is the only one that really worked. Son broke his finger one week before a Caribbean cruise! He swam, dove and enjoyed all the pool & ocean time without having to worry about the cast! Highly recommend 😊

So disappointed
Came very fast. Taking the product out, I noticed it had an odd green color at the top which made me wonder if it has been sitting on a shelf for too long. I read and followed the directions of how to put it on the arm not broken so we could test it in the bathtub. When I was getting the extra air out (the way the directions said to) part of the top ripped very easily. I don’t have long nails and took off all jewelry so I have no idea why it ripped. We continued to test it in the bath and it kept my daughter’s arm dry as advertised, however, it is cutting into her arm where the rip is. I worry that it will rip more each time we use it. We are leaving in 2 days to go to the beach (I know horrible timing for a broken arm on a four-year-old) so I’m very disappointed that this most likely won’t protect her from any splashes. We were hoping she could at least get her feet and possibly legs in the water with this product, but I’m not sure I can trust it now.

Love, but sizing not correct.
To make a long story short, my daughter broke her ankle at the beginning of summer, and because I still wanted her to enjoy the summer we decided to try this based on a recommendation. After this product was recommended to us I went on and started looking. I found this and followed the sizing guide to a T. My hubby and I felt confident this was going to work. After unboxing, I still felt good about it. Because of the material I knew it would be a little bit of a struggle to get over the cast which of course it was. Here is where things went south. The material itself is great, however toward the top becomes very thin and almost feels like it could break. The worst part though was with the fit. It states to measure from bottom of foot to just above the cast (which we did). However when we put it on our daughter it literally sits just above the cast and so when she moves it starts to roll or shift and it becomes too small. At first you think it’s going to fit great it seals nice to leg, but after a few leg movements it is now down to the cast. Not to mention that we had to pull up on it so much that it was squeezing her toes at the bottom. I should mention that her cast is from toes to just below her knee. I guess I said all of that, to say this. When measuring, I would go well above the cast (like 5 inches) and then do the measurement around the leg itself. I would have much rather of had it a little big instead of so tight that it allowed for no movement. Looking back we would have made the protector go above the knee. I am not saying don’t buy the product, I would just be sure you give some wiggle room for the length of the protector.

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

Sumergimos la pierna de mi hijo a la alberca y le entró agua, confiamos y desafortunadamente no funcionó!

Pille el xs para un niño de 6 años , era el que encabaja con las medidas. 2 días de prueba en piscina con muchas horas de uso , ni una gota de agua . No se lo que durará pero para el tiempo que tiene que usarlo creo que de sobra . Única pega , si lo que sella al brazo que es la parte estrecha fuera 5 cm más largo creo que te dejaría más tranquilo de que no le va entrar agua . Lo volvería a comprar y lo recomendaría.

So so pleased with this product! My 2 year old damaged her toe and had to keep her dressing dry. I was worried that this would be too big, or too tight around her leg. I need not have worried about either - it never once leaked, and she wore it for swimming, in the bath, at the seaside...basically, everytime she got wet for 6 weeks! It was never too tight around her leg. It's a rubber material about the same thickness of a rubber glove, and the design of the neck meant it hugged her skin close, but didnt dig in. My daughter had quite a big dressing on her foot and this fit over easily. Also, she often had a water show on the top of it.
