MUSCLE RIPPED is a slimmer version of our best sheath MUSCLE. We made it leaner & a bit shorter so it fits more & fits better. Made add a little more girth and inches of length not too big not to small. Morphs to fit big or small with our ADJUST fit insert so it fits right for you and our original COCKSLING base, so it really stays on, no straps, no harness like its part of you.
