Vintage Resistol 3X Beaver Self Conforming Hand Creased Pecos Cowboy Hat 7 1/8. NOTE: I say 7 1/8 but there is no size label inside. I wear a size 7, and this is slightly larger on me. I measured inside band and got 22 1/8 dia.
I used a cowboy sizing chart which showed this number to compare to a size 7 1/8 - 7 1/4. Its not that much larger on me so I,'m guessing a 7 1/8. The hat is very nice with very little signs of usage. Don't see any stains or smell any smells either. Very slightly dusty, which I cleaned off most.
Again, a very nice vintage hat. Inside band says: Huflins' Buckaroo, Boulder, Colorado.
