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 AirFlow polyamide mesh (94% Polyamide / 6% Elastane): lightweight, stretchy and quick to dry. Built for heat, training and travel. 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.
