How to Find Your Hat Size

  1. First, get yourself a tape measure made from a flexible material like cloth, fabric, or bendable plastic.
  2. Wrap the tape around your head, making sure you measure above your ears at the area where you prefer to wear your hat.

Although it is a matter of personal choice, a good spot to measure is the widest part of your head, as that’s where a hat often fits the best. When you get a measurement, consult the charts above to figure out your size.

Sizing Tips:

  • Measure several times to ensure you’re getting an accurate measurement.
  • Don’t pull the tape too tight; you always want to err on the side of having a little too much room.
  • If you fall between two sizes, we strongly recommend that you choose the larger in the interest of comfort.
  • Head sizes and shapes differ from region to region. The most common male size is 7-3/8 and the average hat size for females is 7-1/4

Love it!!

I love my Isaac Driving Cap!! It is extremely well made and sooooo sooooft!! It's my second hat from The Buffalo Wool Company and can't wait for the Fedora's to come back in stock to add a third!!

Fatfrogaz (Phoenix, US)
Odd(for my melon) but comfortable

For disclosure- I bought this to annoy my teenage daughter. I’ve spent a lot of time and money on this Dad project and this cap was a great addition. Thing is, I actually really like wearing it! It’s warm and soft and was perfect for a two week travel to the PNW. It runs big so size down if in doubt. This will always be in my travel bag except for the occasional school pick up run!

Kurt D. (Carrollton, US)
Really nice cap! But runs large

I really like this cap and the fact that you can roll or bunch it up withut wirrying about ruining it.
Very good quality!
Only issue is thst it runs very large! I ordered a medium and it fits perfectly on my 7 1/2 inch noggin’.

Bill M. (Hercules, US)
Isaac driving cap

At this point, I am unsure whether to try to adjust the cap size with foam under the inner sweat band or to return the cap for replacement with the next smaller size. Unadjusted, the cap slides loosely back and forth on my head.

Michael E. (Eagle River, US)
Happy repeat customer

These are the third and fourth hats/caps I have bought from the Buffalo Wool Company. I wear a hat daily and these are ideal for our Alaskan climate. Almost daily I get complimented on them. I spread the word to anyone who listens. Thank you for offering a quality product. More than worth the proce

Ang T. (Ludlow, US)
Better than I expected!

I ordered this cap for a friend. It was on markdown so I thought I’d have nothing to lose. When the cap arrived, I knew it would be too big. I returned it with special instructions for replacement as I would be away for a bit. My request was honored. The replacement arrived ( in the same box…hooray for recycling!). I know the fit will be correct ( I have my ways). The quality of this hat is awesome. It’s comfortable ( I tried it on for a bit). It will be a birthday gift in November. I’ll update this review, but I can say, without a doubt, the recipient will be over the moon happy! Maybe I’ll even get a photo of the hunk who’ll be wearing it.

Louise B. (Oklahoma City, US)
New cap

Hubby loves his new buffalo hat! He has recently started wearing that style and was surprised at how warm the hat will be. He is looking forward to cooler weather. Thanks so much fir your prompt service!


Bought hubby a hat for Father’s Day. He loves it. A little big, but a size smaller would be too small. All in all we love anything and everything we purchase from you guys.
