Gymnasts and athletes alike use Mueller MWrap pre-taping foam under the sticky tape so your skin stays irritation-free and your hair doesn't get ripped out. Mueller MWrap also prevents blistering when applied prior to tape. Mwrap is versatile enough for non-gymnastics related uses including: holding up sleeves, creating a knee strap, or protecting feet under boots and athletic footwear. Mueller Mwrap can also be used in securing heat and cold packs when you switch from competition mode to recovery mode. Rolls measure 2 inches x 30 yds. Latex-free and water-resistant.
