Made with high-quality rip-stop material, this sauna tank top for men is engineered to resist tearing and fraying through intense workouts and repeated use. DESIGNED FOR PERFORMANCE – Features an adjustable hood for added heat retention, a waist tightening cord for a secure fit, and a kangaroo pocket for small essentials, all in a true-to-size athletic fit workout vest built to last. RELAXED ATHLETIC FIT – True-to-size sauna suit for men designed to move naturally with your body and layer easily over or under training gear, offering a comfortable, non-restrictive fit for workouts, warm-ups, and everyday wear.
