The Alps Extreme Sleeve SFK24-6 New still sealed in factory packaging.

The Alps Extreme Sleeve (SFK) by Alps South was built for all activities and users. The Alps team incorporated their grip gel formula into the Extreme Sleeve to offer better skin adhesion. Greater skin adhesion translates into less constriction or tightness and the tacky gel prevents skin bunching behind the knee for most prosthetic users. In theory, if you experience skin irritation along the sleeve's top edge, their Grip Gel formula should solve this problem.
