This is a super duper, heavy duty compression breathable support for your knee from JOYMOZE. As shown in the pictures, this sleeve gives ample coverage to prevent a knee injury or assist in walking from a knee injury. It is made of a thick elastic silicone with a built-in foam ring that fits around your knee cap. On each side there are bendable stays that move with the flexing of your leg. The sleeve stays in place well. I got a large which fits my husband's leg adequately and gives him the freedom to move around and feel that his leg is secure while working, playing softball or hiking. The blue and gray design is cool enough to be exposed or hidden under slacks. This product is of excellent quality.
I received this product at a discount in exchange for my honest and unbiased review.
