Jaybird & Mais 50 Foam Underwrap has a thin foam substrate that is strong and highly porous. Foam underwrap or pre-wrap tape is used under adhesive sports medicine tapes to aid with painless tape removal and to prevent tape from chafing the skin. It can also be used to help secure bandages and ice packs and to provide comfort inside ski and hiking boots.
