Our Jock Brief, in the front, looks pretty normal, but around the back, the cut-out design is more like a jockstrap. It gives you a cheeky look and a sexy butt boost. The soft elastic waistband gives you all the elements you need for a comfortable fit, support, stretchiness, durability and more. Made of 95% Polyester and 5% Elastane. Blue, Medium. Chest: 38"-40". Neck: 15"-15.5". Waist: 30"-32".
