TRI-SPORT is Oxballs take on traditional metal tri-cockrings. Made from Oxballs' signature FLEXtpr - there is no need to worry about trying to wrestle into rigid rings. TRI-SPORT's super soft material and 3-ring sling design grips for a harder, longer lasting erection and creates a bigger, more pronounced bulge. Each ring is a different size so can be rotated and worn multiple ways for a best fit and varying sensations.
