Prewrap is this foamy, spongy stuff that you wrap around skin before putting tape on. My daughter, and all her friends, also use it in their hair like a sweat band. They go through yards and yards of it. It can cost up to $5/roll, but you can buy it in bulk from Amazon. In rainbow colors! Before I had amazon prime, I had to buy 3 dozen rolls to get free shipping, so she’s pretty much set for her college career, although she’s given all the ugly colors to her teammates. She nice that way.
