My daughter broke her arm playing basketball. She required two surgeries and we had plans to vacation in Florida two weeks after her last surgery. We didn't want to ruin our vacation and we wanted her to be able to participate as much as possible. The doctor didn't want her getting her cast wet and wouldn't put on a water cast since he didn't want her incision to get wet or infected. We didn't know what to do. She had resolved herself to sitting on a lounge chair and watching everyone else swim in the resorts large swim park type pools. 

I started searching online for a solution. There HAD to be a solution. I found one that saved our vacation. It was the Xerosox. 

Description: The Xerosox fits snugly and comfortably, telling you that it is maintaining an airtight, absolutely waterproof seal before you even get in the water. There are no surprises. You feel this watertight seal while you are showering, bathing, or swimming. Get back in the water! Get Wet... Keep Clean and Dry!

The Xerosox works for patients with casts, prosthetics or PICC sites. They have covers for both arms and legs. I couldn't find a local store that carried them but I was able to locate them online finally deciding to purchase from Amazon since we had Amazon Prime for shipping and it was the fasted way to get the Xerosox.
