Inspired by lazy Sunday afternoons, OnePiece created the original Jumpsuit back in 2007. Today, the Oslo-based brand continues to reinvent the art of slacking with their line of innovative leisurewear. Their recently released Spring/Summer ’15 collection was inspired by the diverse groups of people they met while country-hopping over the last few months. Think fresh and clean pieces in a range of summer colors that always keep comfort at their core. Gear you can mix and match. Whether you’re lounging on a plane, binging some Netflix, or just bringing a bit of comfort with you wherever you go, OnePiece is there for the confident trendsetter.
