I'd like to chime in as the past owner of an Akubra. While it was not a Fed IV (they didn't make them back then) it was (I think) a Snowy River. I purchased it down-under on a business trip to Sydney about seventeen years ago. That hat was the nicest hat I ever owned (until my Henry shows up next week.

)
It cost me about $80 US at the time. I wore it all the time, took it adventuring on horseback in the hills of Tennessee and Virginia, hiking in Colorado & Arizona, you name it. I tore the lining out when it got loose, didn't affect it. I had it re-furbished in Prescott, AZ. I filled it with water from streams and watered the horses with it.
The color stayed even despite all the sun exposure, the sweatband never bled, the hat did not shrink, it resisted water and wind. If it tapered I did not notice it.
I really loved that hat, doubly sentimental because I acquired it in Australia while riding in the Victoria Alps.
It was eventually lost to a girlfriend who shall not be named. She's long gone, wish I still had that hat...
I'd give it an easy 8 out of 10. If the Fed IV is even half as well made, I think it's going to be tough to deny it a very high rating on this list.
