Mack Weldon is releasing its first all-new underwear design in almost two years with the launch of the high-performance Stealth Boxer Brief. Designed to feel like a second skin, the Stealth uses body mapping technology to give you airflow and elasticity where you need it and hybrid seamless construction allows for a streamlined design that perfectly conforms to your body. It's a design that's great for workouts and is more than comfortable enough for everyday use.
