This is a sleek, low profile knee sleeve, that won't hinder you as you move on the mat.$25
I measured and I am 15 5/8", do I squeeze into a medium or get a large?
Large will be a bit more comfortable but will slip around more if you're using them for BJJ; Medium will offer better support if you don't have problems with circulation in your calves or feet.
These do help prevent any type of "burn" but they constantly slip down. They have to be pulled up every now and then when sparring :/
