Excellent sports knee brace. Made of thick neoprene material, elastic enough. It takes a little effort to put on and take off, but it is the only one that doesn't fall at all due to its curvature. The most important thing is that it perfectly supports the knee and the muscles that support the knee, and also warms it up during exercise. This way, it doesn't get tired from exertion and protects it from any injuries. It's worth the money. I bought a second one after trying the first. I highly recommend it without hesitation.
