I bought some off brand knee sleeves and compression socks, and they were so inferior to Onecompress. As a fuller woman, typically a 3X in clothing, Onecompress XL was a perfect fit in the knee sleeves and compression socks. They gave me confidence and protection during my Fibula fracture recovery. I wore the knee sleeve on both knees because the uninsured leg/knee got a workout when not putting full weight on injured leg. Both sleeves and socks were perfect for a 6 hour flight I went on too
