I received the FitWearz lightweight breathable knee brace in exchange for my unbiased honest opinion. It came with a nice carry bag. It helps relieve pain. Ot can be used for either your left or right knee. Its made of neoprene which is lightweight and breathable material. Easy straps for it to be adjusted to any pressure that you prefer. This is a great help for people who have pain in their knees from injuries possibly even arthritis relief.
