Another vote for the Tilley (which I bought when I was under 30!). It's awesome. A little chilly in 34deg rain, but then other options come out for the cold weather.
I prefer the model with the darker under-brim, to cut down on glare in bright sun. I also replaced the cotton shoe laces for the strap system with paracord and came up with my own knot system to adjust things back and forth.
It's been through some good times, Grand Canyon, Middle and Main Salmon Rivers in Idaho, Rogue and Illinois Rivers in Oregon, seakayaking in Canada, and various hikes in the northwest.
Here's a
shot of the hat, though I'm still attached under the water...
How many different styles of hats can you see here? (Grand Canyon trip)
