Input:
I am a member of a GORE-TEX product testing team and received this hat a sample while working at a gear store about 5 years ago.
That said, these hats are great. They last forever (mine doesn't show any wear and tear and my father has had one for at least 10 years) and are very functional.
I will readily admit that they aren't the most stylish thing out there, but whether you're venturing out in the rain, wind or sun, this hat does a great job of protecting you from the elements. The brim keeps rain off the face and back of you neck and shades you from the sun. The velcro patches make it easy to hold the sides up and the chin cord ensures that your hat won't run away from you.
I use mine primarily in the rain and on river trips - they are warm enough that I don't love using it in the middle of the summer when it's hot and sunny out (although I have used it for that purpose on occasion).
The Sombrero's light and packs down enough that it will easily disappear in a back pack.
All in all, a great hat if you pick function over form.
