Safety Clothing and Personal Protective Equipment Design Nutty Buddy Flex Athletic Cup Male Genital Athletic Protection Cup by Dosun Shin The Nutty Buddy Flex is an athletic protective cup for male athletes. The cup follows an anatomical shape and is made by injection molding, with a polycarbonate shell and a thermoplastic elastomer overmold. The soft elastomer edge extends along the side areas, so contact with the skin is cushioned and a more comfortable fit is allowed during active body movement. Impact forces are absorbed and distributed more evenly across the pubic bone and soft tissues. Three sizes are offered, and the cup fits into existing sports pants and jock straps.
