The Protective Cast Cover is a cover you wear over your cast. It is made of fabric, any kind of fabric, waterproof, warm, breathable, what ever kind of fabric will work for an individual's needs. For arms it covers the whole arm with a mitten hand over the top of the shoulder. Some of them are shirts, just depends on what the individual request. The cover for legs covers the foot to the top of thigh and can be made as pants, or as shorts on the opposite side of the leg with the cast. If they are in double casts, then both sides would be made the same. This works for arms or legs. Again, just depends on what the individual request. The protective cast cover is meant to keep sand, or debris or even water out of the cast, and give people less stress about their situation.
