LP Extreme Open Knee Support with Posterior Strap, Fully Adjustable Coolprene Knee Brace - Arthritis Pain Relief, Knee Compression Support & Patella Knee Support, Black - One Size

i have a very bad knee and it pains like hell when i play. i used it for badminton and i could feel the difference. I even used it for almost 7 hours on a sunny day and it was not at all uncomfortable. In fact it helped reduce the pain around the knee to a great extent.Highly recommended
