MUSCLE RIPPED is a slimmer version of our best sheath MUSCLE. We made it leaner & a bit shorter so it fits more & fits better. Designed to add a little more girth and inches of length...not too big not to small. Made of our rubbery FLEXtpr so it stretched to fit bigger guys, and morphs onto smaller guys for the right fit. Comes with our ADJUSTfit 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.
