I'm kind of a hat collector as well since my already short hair is starting to thin. I keep boonies in every vehicle and every bag and have several hanging in various places in the house. My current favorite is the under armour tactical bucket hat. Stupid name but the hat is amazingly cool and comfy, even in 100% humidity. I got it for as a birthday present because I am too cheap to spend that much on a Boonie, but I may have to get another when this one wears out. Lifeguard style straw hats are great too. I keep one on my riding mower.
