We make things that will last. Life isn’t disposable, so we don’t make disposable things. It’s no good if it only looks good. It needs to perform, too. Pieces that last longer than a moment, beyond a season. We design for a long life because we value a life well-lived.

We take sweatshirts very seriously, and the Foundation Hoodie is darn close to perfect (if you ask us). This hoodie is simple enough to be your favorite, go-to sweatshirt for hanging out at home, but small details like exposed flatlock stitching at the join seams and the raglan sleeves create a refined aesthetic that allows it to be taken out into the world as well.
