A NOTE FROM THE FOUNDER
Growing up with a big head and a unique style made finding clothes, especially hats, a challenge.
After studying design and working in tech, I realized I wasn’t fulfilled.
That changed when I got tired of ill-fitting Snapbacks and I found my true mission: creating hats for big-headed people like me.
After two years of refining the design and quality, I’m proud of the hats I now offer.
Thank you for trusting me with your purchase. If you're not happy with your hats, reach out and we'll make it right by exchanging them or refunding you.

Founder, Mammoth Headwear

FREQUENTLY ASKED QUESTIONS
Most of our hats fit sizes 7 3/4 in up to 8 1/2 in, if you know your size then our regular hats will fit your big head.
If your hat size is bigger than 8 1/2 in, look for the XXL in the name of the hat or use the filter.
If you don’t know your hat size, watch our size guide video tutorial above on this page.
Our hats are deep enough so they don't sit on top of your head or push down on your ears. We thought of everything when designing our hats for big heads.
Every single one of our hats is made with the highest quality materials that are durable and comfortable. Some customers have had their hats for years - and you will too!
We recommend using a white cloth with warm soapy water. Spot clean it using the cloth on the tip of your finger.
