GYM Jockstrap
The GYM Jockstrap Old School Swim/Run Jockstrap in Black combines a narrow 1" waistband with a breathable nylon-blend knit pouch and matching black leg straps. This men's athletic supporter brings the streamlined Swim/Run profile into the Old School line, pairing minimal coverage with the unmistakable look of a traditional jockstrap.
The black pouch, waistband and straps create a cohesive, masculine silhouette, finished with fine contrasting waistband stripes and a classic front GYM label. Compared with the wider bands in the Old School range, the slim 1" waistband leaves more of the waist and hips exposed while preserving that vintage locker-room character. The textured pouch blends nylon, cotton and rubber for support with stretch, and the open back keeps the look confidently revealing. Choose black for a darker take on heritage athletic underwear, whether worn beneath gym shorts or enjoyed for its stripped-back style.
