Review: Great at first, but low quality so doesn't last. - Full disclosure, I use these when Training BJJ, so there's more contact/friction than a lot of potential uses. The design is great, it keeps the knee really stable, allowing for a full range of movement, and it's comfortable. Problem appeared quickly which was that the stitching on the fabric which covers the metal hinge started to wear away. It finally got to the point where I felt I needed to return iot, but that was more than 30 days, so the company won't replace it. Worth noting that they said they wouldn't do that anyway for desertcart orders. Review: Stabilizes!! - This brace provides me the stability needed before my upcoming surgery.My knee is unstable and I needed a brace as prescribed by my ortho office while waiting on surgery. This makes walking and going up and down steps much more pleasant as these activities were painful prior to placing the brace. Do not hesitate to get this item if you are on the fence. It is important to measure. If you are in between sizes and are a smaller individual size down. ## Features - Patented Drytex Material: Breathable, moisture-wicking material for cool and comfortable wear.

I have larger than most thighs and calves. Xl is too small.** A: I am not sure abt this .slightly tight feel is not too bad as it stretches slightly and it has Velcro as well to reinforce both top and bottom areas . **Q: What are the measurements for the donjoy performance bionic drytex hinged knee sleeve?** A: returned this product because even though I measured following their directions I could not get it on. **Q: Can this brace be used in water (eg surfing)?** A: Yes I use mine for surfing to make the brace last adjust slide it on before surfing & slide it off if you keep using the Velcro on & off it will wear out prematurely ## Customer Reviews ### ⭐ Great at first, but low quality so doesn't last. *by M***S on 14 July 2022* Full disclosure, I use these when Training BJJ, so there's more contact/friction than a lot of potential uses.
