About Son of John

Son of John is a fast-growing Amsterdam brand making the perfect boxer short: crafted from shirting-grade cotton poplin, breathable, comfortable, and without itchy labels. We're a brand that focuses on just one thing, and does that one thing a little better than anyone else. We're expanding from the Netherlands across the EU, with our sights set firmly on going worldwide. We're looking for people who love building something from the ground up, and want to be part of the ride as we grow into something bigger.
