Pre-wrap also known as MWrap®, underwrap and pro-wrap is a multipurpose roll of foam. Originally designed to go underneath athletic tape to protect the skin from tape. Widely popular by athletes as a non-slip headband. Pre-wrap easily tears from the roll and can be made into the perfect-sized headband. The unique nature of the foam clings but is not sticky. Note that variation of roll size is normal due the stretchy nature of the product and how tightly it is rolled. Rolls are measured in yards, not width of roll.
