My son Collin is 8 years old. This June 2009 he fell off a skateboard and broke his arm for the third time this year. I was devastated and him even more so. His second summer in a row with a cast which to him meant no swimming. I immediately started searching the internet for a miracle. I found our miracle; Dry Pro cast cover. That cast cover saved his summer. He went out on the lake tubing, swimming several times a week, and even going down water slides and jumping in. Because of the numerous fractures, he was placed in two different types of casts over a period of 7 weeks. I bought two cast covers to get us through. I have since given one to our orthopedic office for advertisements. Everyone needs to know about this product.Thanks again Dry Pro!!!!
