These are excellent hats. I wound up buying a second one, since I wear the first I purchased at work; I work in a hot environment and have to wear a hat, and these breathe perfectly and don't get sweaty or really pick up smells badly over time. The first one I bought suffered an unfortunate incident with a cat, and thinking it was ruined I ran it through the washing machine just to have a small chance of saving it...and it came out perfectly clean, still in shape, and was good as new.

They're well constructed, they look sharp, and they hold up to accidental mistreatment and daily use just fine. I had an older wool 504 that I quit wearing because the band wore out and it wouldn't keep shape well, but these ventairs seem to be much more sturdy and reliable than my older 504 was. I'm really happy with it, to the point that despite having two already I might order a couple more in different colors. Just a great year-round hat that looks good with almost anything.
