About OnePiece

OnePiece manufactures and sells casualwear clothing such as shirts, hoodies, pants, and their original Onesie. Early one Sunday morning in 2007, Henrik, Knut and Thomas, three Norwegians in their twenties, fantasized about the ultimate chill-out wear that would be perfect for a lazy day at home. They all agreed on the merits of the sweatsuit for recovering from a night on the town. "But without the tight waistband and the pressure to go jogging," Thomas said. Knut had been staring at a light bulb when, eureka, it all became clear: "Why not sew together a hooded sweatshirt and a pair of sweatpants? Let's make it so big that no one in their right mind would think of working out." "If we can skip the waistband, I'm all for it," said Thomas. "But how are we going to get into it?" "No sweat," replied Henrik, "we'll just put in a big zipper." And with that the OnePiece Jump In was born
