Standard adult wraps are 180"
Standard Jr/Child are 120" Also sold as "MMA" wraps
Wraps sold at Sporting Goods stores are usually 120-160"
Wrap width varies, usually about 2" up to about 2 3/4" I believe
"Gel" or wraps that are more than just a long piece of fabric are garbage
Regular are herringbone cotton fabric. I do not like them, some do.
Mexican are semi-elastic, form tightly to the hand. I prefer them.
