I bought this for tendenitous in my elbow. It's classified as golfer's elbow, but it was caused by boxing (pad work). I found out from my doctor (ortho) after the fact that I needed a strap to wrap around my forearm right before my elbow. So I figured I wasted my money. However, I realized that I could fold over (double-up) this wrap in certain spots and it acts like a strap. So it can be used as a full elbow support, protector and strap. The best part is I can carry it in my back pocket and throw it on whenever needed... pick up a box or the dog or open a jar, whatever. It says not to, but it's definitely machine washable. It's very sturdy with thick material and great elasticity. BTW, I now own 3 to cover laundry days.
