Frequently Asked Questions (FAQs)

1. Do waterproof cast protectors work?

Do waterproof cast covers really work? Cast covers from reputable companies are very effective. As a user, you have to ensure you get the right size for you, put it on correctly, and use it as recommended. The brands we recommend are TKWC for leg cast covers and DryPro for arm covers.

2. How do you protect a cast while swimming?

Invest in a high quality cast sleeve, cast cover, or cast protector which has a 100% watertight seal and which is designed for bathing, showering, and/or swimming. The strongest and most effective cast protectors allow you to fully submerge in water without fear of getting your cast, bandage, or splint wet.

3. How do I protect my cast from the rain?

Keep your child's cast dry during baths or showers by covering it with two layers of plastic, sealed with a rubber band or duct tape. Avoid swimming while wearing a cast that isn't waterproof. A fiberglass cast that has a waterproof liner can get wet.
