Good foundations make good outfits. That's why at UNIQLO, we take men's underwear very seriously. With soft, breathable pieces made of the world's most innovative fabrics, men's underwear from UNIQLO is unlike anything you've ever seen (or felt) before. These boxers and boxer briefs are light and cool to keep you comfortable all day.

If you like a brief, try our Supima cotton briefs — made from the world's finest cotton, they stay soft and supple all day long. For breathability, try a boxer brief made of AIRism fabric. With moisture-wicking and quick-drying functionality, you'll always stay cool. For the traditionalist, boxers made with crisp Oxford cotton will suit you under your suit.

With so many styles to choose from, UNIQLO is just the place to find your new favorite pair of men's underwear.
