Pro-Tec Athletics RM Extreme Contoured Roller Massager is a handheld roller massager that gives you a controlled deep tissue massage. The contoured surface effectively wraps around select body parts including hamstrings, quadriceps, calves, back and more! The non-flexible design provides leverage so you can control the compression level. The RM Extreme is made from a non-toxic, latex free, closed cell EVA/Polyolefin Foam and is 21" in length. Very easy to use and keep clean.
