Blank Trucker - Hi-Vis Green

If you know your hat size, our hats fit sizes 7 3/4 up to 8 1/2. If your hat size is bigger than 8 1/2, check out our XXL hats here

If you don’t know your hat size, watch our size guide video tutorial.

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.

If you’re not happy with your hats, we'll give you a prepaid label (US orders only) and you can send it back for a full refund within 30 days of purchase.
