Shock Doctor's Core Supporter Brief with Cup sets the bar for Men's protective gear. Shock Doctor has created the ultimate support and protection for young men of all ages and sizes, that compete in contact sports. Our team of physicians, athletes, and engineers know all too well how supreme groin protection is vital in any intense sport. Combining science and experience to create the pinnacle of protective gear, the 218 support strap checks all the boxes and more. SD's X-Pocket Cup Retention System positions the cup in a more natural position between the legs for a closer, more comfortable cup fit. This prevents chaffing and uncomfortable positioning to help you maneuver, defend, and stay in the game without having to slow down, or adjust. The Shock Doctor Core jock strap was constructed using moisture-wicking technology that eliminates sweat as you go through vigorous workouts, plays, or extra innings. The four-way stretch fabric also keeps you mobile as it moves with your body when you move better than most fabrics. The mesh cup pocket is a secure area for you to slip your cup of choice. It will increase ventilation to keep your body cool. The comfort waistband does not irritate your skin, keeping your mind off your comfort levels and on the goal.
