You can feel the difference straight away. thick, solid and properly stitched. These feel robust, not disposable gym gear + i got free wristbands with my order.

They’re tight getting on, but once they’re on…...they’re locked on. No slipping, no adjusting between sets. Just proper knee support you can feel.

10/10. I've been using these knee sleeves for heavy ish squats and high-rep sessions. Enough support to feel stable and let you move naturally.
