The CalExotics Advanced Silicone Pump Sleeve transforms any 3-inch penis pump into a luxury experience. The flexible, stretchy silicone eliminates uncomfortable direct suction, creating a totally protective and luxurious pumping environment.

Penis pumps work by creating an airtight seal and suction that encourages blood flow into the penis. In the short term, this produces harder, more reliable erections; over time, pumping encourages measurable growth in both length and width. This premium sleeve is made from high-quality, body-safe silicone and simply slides onto your pump's cylinder base for instant upgraded comfort.
