The silicone VacuGlide Power Pulse Sleeve turns VacuGlide’s dynamic suction into bigger more dramatic waves of pleasure. The Power Pulse’s 14 ribs compared to the Classic Sleeve’s 35 ribs mean that you’ll distinctly feel each rib sliding up and down your penis. This is a more aggressive texture built for edging and more intense play. If you’re ready for a new pleasure challenge or have grown accustomed to original sleeves, you’ll love this upgrade!
