Slightly roomier than our Slim Fit: eases slightly over the butt and through the leg. Men who prefer their underwear with a fly will be happy to see this feature. Designed to deliver maximum softness and breathability, the best-selling Ultra boxer brief is an essential everyday item. Made using a premium viscose that’s both naturally moisture wicking and odor resistant, this pair is the perfect all-day companion. When it comes to breathable underwear, there’s no better bet than Ultra, providing your balls a breezy space to just hang out and chill. Plus, with the patented (a 3D hammock that holds everything in place), you’ll be in the best hands possible. Other features include non-chafing Flat Out Seams™, Three-D Fit™ 9-panel construction, and moisture-wicking fabric. LENZING™ ECOVERO™ certified eco-responsible viscose (95%) and elastane (5%).
