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 92% Modal / 8% Elastane blend: silky soft, breathable and moisture-wicking, so it stays comfortable in any climate. The 5 inch inseam lands mid-thigh, our standard boxer brief length. Finished with a branded 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.
