this thing is a champ if...
This just arrived in the mail. I think I'm going to like it. The 94% nylon / 6% spandex blend is uber freakin lightweight, and feels comfy on my grape already. It sports a 2" brim and a 3.5" crown depth. I think it's going to be an awesome summer hiking hat.
I wear a 7 1/2 to 7 5/8 in fitted caps and the L/XL just fits. The color scheme in the Calico is saucy and fun. I will wear it hiking tomorrow and update my review.
Edit/Update: I knocked out a 7.5 mile dayhike today in sunny conditions and this thing is a champ if it fits you, but it was just snug enough to start bothering me halfway into the hike. I will be returning it and sticking with my OR Sun Bucket and Patagonia Bucket hats for now.
