6 INCH Synthetic Cast Stockinette by OrthoTape (1 roll 25 yards.)

OrthoTape 6-inch compression stockinette is a high thread count, synthetic tubular sleeve bandage that maximizes support and minimizes constriction.  Synthetic tubing sleeve provides good compression and support as a liner for the skin when worn under compression wraps, knee braces, amputee products, as wound dressing, and orthopedic casts. It is also commonly used as a pull sock for applying arm or AK prosthetic sockets.

Note for sizing: Need to know what size stockinette to order. Measure the circumference of your leg or arm. Stockinette is measured in width so basically, it is the diameter value. So you would double the value. For example, a 3" stockinette has a circumference of 6", 4" stockinette has a circumference of 8". Stockinette will stretch some, so you have about 0.5 to 1 inch of stretch to that circumference value.
