The SHEATH 4.0 is our flagship and most popular design: a 5 inch boxer brief built around the Zen Pouch™ Duo.
The Zen Pouch™ Duo is what sets SHEATH men's pouch underwear apart: two pouches that separate and support, so there's no chafing, no sticking and no adjusting. A vertical fly keeps it practical.
It's made from our Bamboo AirFlow mesh (88% Bamboo / 3% Polyamide / 9% Elastane), pairing the softness of bamboo with an open, breathable knit that moves air. Ideal for warm climates and hard workouts. The 5 inch inseam lands mid-thigh, our standard boxer brief length. Finished with a geometric athletic waistband.
Your First Pair Is Risk-Free. If SHEATH isn't right for you, our First Pair Guarantee has you covered. See Shipping & Returns below for details.
