Given that the word “athleisure” is officially entering the Merriam-Webster dictionary next year, we can safely surmise that this whole lifestyle approach to fitness and fashion is not just a passing fad. And that’s a win for everyone and everything, including your packing list. Stretchy leggings, bouncy sneakers, and boxy hoodies are not only damn comfortable to wear on the plane, during nonstop days, and while you exercise, but they have — in all their casual and accessible glory — gone bona fide chic.To help up your athleisure game for this equally chilly and busy season, we’re presenting the gear from SIX:02 that you’ll want to take along on your holiday travels. From a stylish and supportive sports bra you can pair with a sheer top to skinny-fit fleece sweatpants that can easily be sported in public, these are the multifunctional pieces you’ll want to wear everywhere. Forget about spending a half-hour figuring out how to fit your running tights and sneaks into your carry-on. This is how active fashion girls find their balance.
