Abstract: A prosthetic sleeve for covering a gel sleeve having a reinforced circular opening at the distal end of the sleeve that is sewn or serged and then optionally coated with a gel to prevent unraveling of the yarn. The invention includes a knit sleeve having an upper end, a distal end defining the circular opening for receiving a locking pin secured to one end of the gel sleeve, a perimeter defining the outer boundary of the circular opening formed of serged yarn for reinforcing the circular opening, a gel coating on the perimeter for preventing the overlap of sleeve material between the gel sleeve and prosthetic device, and a coating of gel on the yarns forming a portion of the knit sleeve immediately surrounding the circular opening for providing resilient flexibility to the distal end of the knit sleeve.
