A Tynor Scrotal Supporter is generally designed to be worn directly against the skin for maximum support and effectiveness. It should be worn like a pair of underwear, with the scrotum placed into the pouch and the adjustable waist belt secured for comfort. However, it can also be worn over briefs or underwear if added comfort or extra support is desired, but this is not necessary for it to function correctly. For the best fit, ensure that the support is snug but not too tight, and follow the instructions for positioning to provide maximum support and comfort.
