(Patent Pending)

The SHEATH 3.0 is one of the last models with our classic no-fly Zen Pouch™ Solo, finished with an Aztec geometric waistband designed with our friends at TIMEWHEEL Records.

Our simplest take on men's pouch underwear, the Zen Pouch™ Solo holds everything in a single supportive pouch, keeping it lifted and off your thighs, with a clean, no-fly front.

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.

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.
