I didn't know that, and I've wondered how straw was rated.
The last time I bought a really good hat (about 15 years ago), Stetsons and really good quality handmade western ones were going for around $15 per X. I don't know how it is now.
This thread has got me thinking again that I need a good crushable western style hat, but not as "bulky" or stiff as the ones I have now...shorter crown and narrower brim.
A favorite of Francis Sell.
In the Pacific Northwest we have the crusher hat.
