POWERSLING is a limited edition cocksling modeled after our discontinued, best-selling NUTTSLING. Itâs made from our signature FLEXtpr⢠so itâs rubbery and squishy but still firm enough for some serious sack-stretchinâ action. The soft, flexible material and sling design grips your sweaty sack and shaft and pushes your package up nâ out for a bigger bulge. POWERSLING is perfect for filling out your favorite jockstrap or ass-hugginâ gear.
