Onepiece was founded on a lazy Sunday in in Oslo, Norway by three young Norwegians in 2007.

In an effort to capture the essence of that carefree day in a single piece of clothing, the brand was born. By sewing together a hoodie with a pair of sweatpants using a giant zipper, we created the Original Onesie.

Almost two decades later, we’ve been lucky enough to sell over 3,000,000 jumpsuits to customers in nearly every country on earth, and see Onepiece worn by some of the world’s biggest celebrities.

Today, we’re still in Oslo, still Norwegian owned, and still doing what we do best: making premium, ridiculously comfortable jumpsuits that look as good as they feel, at home or out in the world.
