The MUSCLE BANDIT is the thinnest of the three penis covers we produce in the "MUSCLE" series: the original MUSCLE is thick and long, the MUSCLE RIPPED is long with veins and slightly thinner... this MUSCLE BANDIT is even thinner and a bit shorter, to add extra volume without being excessive. Made from thick Plus+SILICONE rubber, it hugs the shaft, adding extra diameter and a few inches of length. Each cover fits well and includes the discreet, soft rubber ADJUSTfit, allowing adjustment according to the size of your shaft... you can get extra ADJUSTfit inserts in packs of three for an even better fit - we design covers that fit any shaft size. The MUSCLE BANDIT stays in place whether you are hard or soft.
