My last one (Akubra) was a bit too small but was great never flew off and got trod on or forced me to turn around and go back. But took it for a swim while camping and thought it would be smart to dry it out over the fire and it shrunk so bad I couldn't even get it on. It was about 8years old and was only worn where you grab it to take it on and off.
Different lifestyle now, I wear a cap mowing etc for ease with ear muffs.
