Outerknown Utilitarian Shirt
From world champion surfer to sustainability trailblazer, Kelly Slater continues to redefine what effortless style looks like. His brand Outerknown blends classic design with a deep commitment to ethical and sustainable manufacturing, and the Utilitarian Shirt is a perfect example.
Drawing inspiration from vintage military gear, this midweight shirt is built for everyday versatility. The rugged herringbone weave adds texture and character, while an aggressive wash gives it that perfectly worn-in look right out of the box. It’s tough enough to handle daily wear but refined enough to stand on its own or layer over your favorite tee.
Details matter here, double-needle stitching ensures long-lasting durability, while two flap chest pockets and a pen pocket deliver real utility. A subtle OK logo embroidered inside the placket ties it all together with understated style.
Whether you’re on the move or kicking back, the Outerknown Utilitarian Shirt captures the balance between function, comfort, and conscious design, a timeless piece made for those who care about what they wear and how it’s made.
