The Story
Founded by three friends from Amsterdam.
About Son of John
Son of John is built on a simple belief: the garment you wear more than any other deserves more attention. You sleep in it, you start and end your day in it, and yet almost everyone treats it as an afterthought. We turn that around.
We make premium loose-fit boxer shorts from 2x100 shirt-grade cotton, the same fine cloth used for premium dress shirts. Light, breathable and exceptionally soft, yet made to last. Designed in Amsterdam, built on more than thirty years of craftsmanship, and dedicated to doing one thing perfectly.
Our story
We grew up in Germany, Australia and the Netherlands, where almost nobody wore loose boxers. In Amsterdam, they were the standard. They looked better and felt freer. Yet every pair we found was either a jokey student print or an afterthought from a big underwear brand. Nobody made a loose-fit boxer of real quality, with a timeless design, at an honest price.
The answer was closer than we thought. For more than twenty years, John Crocket, the suits-and-shirts brand founded by Oskar’s father, had been making boxer shorts from the same cotton as its dress shirts. Oskar had worn them for years. The product already existed. It had simply never been brought to the world.
So the three of us set out to do exactly that. Oskar brought the product and the clothing expertise he grew up with. Rijk brought the business. Boris brought the technical side. One shared standard: never release anything we don’t stand behind one hundred percent.
The Name
Son of John is a tribute and a fact. A tribute to the craftsmanship of John Crocket, where our boxer comes from. And a fact: Oskar is the son of its founder. The name connects thirty years of expertise with a new generation carrying it out into the world.
Made to Disappear
A good boxer disappears the moment you put it on. That’s why there’s no label on the inside. Why the waistband is woven into the fabric, not stitched on top. Why the fly is sewn shut at the bottom. And why the thin, supple cotton gives you the freedom of a loose fit without riding up. On the outside, a small contrast logo sits on the right rear, at the same height as the tab on your jeans. Recognisable, without shouting. Every fabric variant is externally tested before it joins the collection.
On 8 October 2024, Son of John was born.
The Mission
Our mission is to redefine an overlooked essential by bringing wide boxershorts back with true craftsmanship and integrity.
We focus on one product and make it exceptional – using premium shirting fabrics, precise engineering, and thoughtful details to create underwear that feels effortless every day. Lightweight, breathable, and built to last, without irritation or compromise.
Premium craftsmanship at a fair price.
The Vision
Son of John exists to set a new global standard for men’s underwear.
In five years, we want to be known worldwide as the brand for loose-fit boxer shorts, grown by word of mouth rather than loud advertising. In ten years, the loose-fit boxer is no longer a category but the standard. For every man, in every generation.
And the boxer itself? Still the same one, only better.
