Dad Hats & Baseball Caps

Soft, unstructured dad hats with embroidered boxing and MMA designs. Broken-in feel from day one — low-profile, curved brim, adjustable, fight-approved.

Dad Hats That Feel Like Favorites On Day One

The dad hat is the most-worn hat in America for a reason: unstructured cotton that molds to your head, a low profile that goes with everything, and a curved brim that doesn't shout. Ours keep all of that and add what the mall versions don't have — original embroidery from the fight game: the Red Boxing Gloves dad hat, Blue Corner, Cartoon BOOM, Work Harder, and the King Killers crest.

Every hat is adjustable strap-back, one-size-fits-most, embroidered for durability, and finished to order in the USA in about 3–6 business days.

What's the difference between a dad hat and a snapback?

Structure and posture. A dad hat is unstructured with a soft, pre-curved brim — it relaxes and molds to your head. A snapback is structured with a flat brim and a snap closure — it holds a sharper shape. Dad hats read casual; snapbacks read fight-night. We make both: see snapbacks and trucker hats, or browse the full Hats & Caps collection.

Do dad hats fit big heads?

Yes — the unstructured crown plus adjustable strap-back gives the widest fit range of any hat style, comfortably covering most head sizes. If you're between fits, dad hats are more forgiving than structured caps. Free US shipping over $100 and a 30-day money-back guarantee on every hat.
