Last year Spanx tackled guys’ guts with a tummy-tightening line of undershirts. This fall, they’re taking it below the belt with the launch of bum-sculpting underpants. Spanx for Men Comfort Cotton Briefs and Boxer Briefs will incorporate the same curve-correcting technology as the women’s line–with men’s special needs in mind. “We wanted to give them really comfortable underwear with benefits,” explains the brand’s founder Sara Blakely. In addition to drawers, there is now an update to the tees with the Zoned Performance undershirt. Prices will range from from $38 for the brief to $48 for the boxer brief and are available at Spanx.com and major department stores.
