Originally designed for power lifters but quickly adopted by the cross fit community. These neoprene knee sleeves are 5mm thick to give support, protection, compression and warmth to the elbow area but still allow flexibility and movement. They are excellent for power lifting and weightlifting, also great for Cross Fit WODs or any sport where some elbow protection and support is needed. Elbow sleeves help athletes by increasing blood flow and reducing pain, not only during but also after performance. Compression is important because a compressed elbow encourages blood flow through the blood vessels of the knee. These sleeves add warmth and limit joint movement, these two things are vital in injury protection. When you are injury free your performance will increase and so will your concentration. Made from 5mm thick Neoprene with reinforced stitching these knee wraps provide extra support and warmth for your Elbows. The comfortable ergonomic design is robust and durable.
