Don"t fumble with plastic bags and tape to make a cast waterproof - use SEAL-TIGHT Freedom coverings instead. The key is the SEAL-TIGHT Freedom watertight seal, a flex-seal rubber diaphragm that slips over the cast and fits your leg or arm squeegee-tight. The diaphragm creates a uniform seal around the limb and permits drainage of water away from the cast protector. The vinyl arm or leg bag is durable; it is abrasion resistant and minimizes slippage while showering. With 4 sizes to choose from, you"ll find the exact size you need. SEAL-TIGHT Freedom will withstand daily use during the life of a normal cast.
