Collection: One Piece Briefs and Underwear

A true One Piece fan doesn't stop at a T-shirt or cap: passion can slip beneath your clothes too. Our One Piece boxers and briefs collection brings together more than 100 printed designs, from faithful portraits of Monkey D. Luffy to scenes featuring the entire Straw Hat crew, along with nods to Trafalgar Law, Shanks, and Emperors such as Buggy the Clown. Enough to turn everyday underwear into a discreet little tribute to the Grand Line.

Cut for optimal everyday comfort, these garments feature all-over or centered prints, ranging from manga-style black-and-white artwork to the vibrant colors of the anime. Whether you're looking for understated boxers with a simple Jolly Roger or humorous briefs featuring Tony Tony Chopper, every design is made for fans who love to wear their passion down to the smallest details, from waking up to the New World.
