When my daughter broke her forearm at the beginning of summer, I knew we would have to have a cast cover. We already had our vacation booked and I couldn’t bear the thought of her sitting out while everyone else went in the water. I did some research on other products and then I came across the Bloccs Cast protector. I knew it when I saw it online that it was the one we had to have. It has served it purpose with 100% effectiveness. It has kept the cast dry through bathing/showering, the pool, the sand and the ocean. It was worth every bit of money I spent. Highly recommend this cast protector to anyone that is looking for this type of product.
