HALF LEG WATERPROOF CAST PROTECTOR: durable, reuseable and easy as 1-2-3 to use. Just slip on over the cast, splint or bandage. Place the opening of the waterproof protector at least 1" above where the cast stops. Pump out the air using the attached bulb. When the bulb is completely flat it is completely waterproof. Once you are done simply slip two fingers into the top of the waterproof protector letting the air back inside. Then simply slide off.
To determine the size of the half leg protector measure the actual leg at least 1" above where the cast stops.
SMALL HALF LEG fits 10-13 inches
LARGE HALF LEG fits 13" and Up
