I've had my River Guide for about 2 years. I fold it up, cram it in my luggage, and it bounces back when I put it on. I got compliments on the hat from locals in Guatemala and Ecuador, not that it matters but it just proves this is a good looking hat. This is my daily wear hat and I sweat on it a lot, get it dirty, smokey, drop it in the mud, etc. I just wash it with cold water, use a little soap on the sweatband. The sweat is causing turquoise colored corrosion on the chin strap eyelets. Not an issue so far and actually ads character. You can't go wrong with this hat. Perfect pack-able/crush-able hat for travelers.
