Tubular cast stockinette is the first layer applied during a medical cast application. We have a variety of colors available from black, blue, green, red, grey, hot pink, and more. This layer helps to wick sweat from the body. Cast padding is rolled over top of the cast stockinette, followed by fiberglass or plaster casting tape. It is quite useful under bracing products such as a cam walker or knee brace to keep the brace from coming in contact with sweat, keeping it clean and sanitary. Stockinette for leg or arm. NOTE: The stockinette on this page is not waterproof. For waterproof products see our waterproof cast kits.
