Given the popularity of adult onesies, it was only a matter of time before someone tried to exercise in one, similar to the new Lululemon running onesie. Whether anyone saw the 'runsie' coming is difficult to say, but it will definitely have people talking.
While a sports bra is sold separately, this one-piece running outfit means you don't have to worry about matching your athletic gear (if that was a concern you had to begin with). Made to keep the wearer cool while going for a run outdoors, the Lululemon running onesie features a cut-out back design as well as handy pockets to store essentials plus a secret one for keys. The athletic romper is also made out of breathable material that 'sweat-wicking.'
