These PUMP Jock Boxers will change the way you think about underwear. With a built-in jockstrap (front pouch and rear straps), this pair will hold and lift your bum and bulge for a fuller look. The ultra-soft cotton blend makes this pair feel even better than it looks! They will tempt anyone lucky enough to see to in the locker room, bedroom, or anywhere else you rock this stunning pair. Materials: 95% Cotton, 5% Spandex Sizing: Manufacturer size Large (36-38” waist guidance); however these appear to run Smaller (see picture of measuring tape on waistband). Given actual measurements I’d say these should fit more like a Medium. Also note that these are very low rise.
