WSI HYPRTECH Bamboo Boxer Briefs with Fly

Choose an everyday underwear layer with room to move and a soft, moisture-wicking feel. WSI HYPRTECH Bamboo boxer briefs combine a contoured pouch, built-in fly and relaxed, low-compression fit, making them a practical choice beneath work clothes or casual clothing. Stretch fabric follows your movement without relying on a tight compression cut.

Choose Black for the plain black waistband or USA for the black body with a flag-pattern waistband. Both versions use the same brief design; the 7.25-inch inseam is the manufacturer’s measurement for Large. Check WSI’s body-size guide, and line dry after washing to help care for the fabric.
