I wore this hat daily through an entire 6 month season as a Biotech with the N.P.S. Worn through monsoon rains, scorching sun, beat to heck, (in Northern AZ)and it held up great. Light, comfortable, the neck cover thingy works great, although I was told I looked like a terrorist while wearing it with that attachment. I've thrown it in the washer about 4 times now and it comes out looking new. I'll be doing another season this summer, and I'll be wearing it daily again. Also, I have an enormous head, I had a ranger type hat once and it was a xxl, extra long oval, and the largest size of this hat fit fine with an adjustment of the strap. Highly recommended. Looks good without the neck protector btw.
