I see so many different kinds of hats on the trail, reminds me of the song Easter Bonnet. And with so many Yuppie brands and big bucks to be made, most outdoor gear fitters have an extensive inventory of models available. A hat can be critical for survival or comfort given a “Perfect Storm” of conditions to threaten the hiker’s well being in the wilderness. I almost always take a hat, but most of the time it is inside or strapped to the outside of my pack.
