measured my head, determined med/large. Bought the large but it seems, maybe stretched out ? It is way too big for me. I don't want to exchange in fear the med will be too small. No adjustment strap, so it is what it is.

I love them. Got the plaid, the black, and the charcoal diamond. They fit and look fantastic. My only complaint is you only have 4 to choose from. Please make more. They're the best hats on the market.

I love these hats. Best fitting hat I’ve ever had

The Jack is the perfect hat. Hands down the best. I have purchased 6 hats thus far, 4 Jacks! The best fit. The best for style and comfort. I have tried multiple competing brands. And King & Fifth continues to lead the pack. I just wished The Jack came in more colors

Thanks K&F! I love my new hat. The style and quality are amazing. It fits better than most hats I’ve ever owed but I do have a suggestion. Most hats are way too poofy in the circled areas of the picture that’s I’ve included. They don’t sit flush to the head and this true with your hats as well although it is way less. Still looking for a hat that sits flush on the head in this area. Just a suggestion. Would love to see it. Thanks!
