The SHEATH 4.0 is our most popular model to date, featuring an athletic-style waistband and our new Dual Pouch technology. In terms of isolation from the thigh region, the Dual Pouch achieves an even higher level of comfort than our Single Pouch design for those truly stifling days, coming equipped with a circular seamed urination hole that allows for a gentle and unobtrusive separation between the penis and testicles, and a fly for quick access. The SHEATH 4.0 will truly change the way you think about your underwear.
Superior Boxer Brief Comfort – The 4.0 is made to support your every move and provide a lasting comfort with its cool, form-fitting compression and revolutionary testicular isolation.
Supportive Dual Pouch – A signature design for our active underwear, the circular dual pouch provides better separation and comfort when running or on the move.
Breathable, Flexible Fit – Our underwear boasts the ideal blend of 95% modal and 5% elastane to ensure moisture-wicking fabric that reduces chaffing.
Enjoy Active Fitness – The smart choice for runners, CrossFit athletes, martial artists and other on-the-go lifestyle.
Classic Colors and Patterns – The SHEATH 4.0 features a wide array of color options to fit every man's style.
