    Great Moab hat!!!!

    • Fit: True to size

    I got this for sun protection when I take trips down to the desert. This is very lightweight and also very breathable. Not only does it shade your face and neck but it has sun protection built into the material which is super helpful. I love how this has chin cord that you can take off. I took if off the first day I got this and have not yet had to put it back on. If there is a windy day in my future then I am sure it would come in handy. It also is not very loud and comes in some colors that appeal to me. Hit me up if you have any questions on this hat.

    Serious coverage for extreme sun!

    • Familiarity: I've put it through the wringer

    When im out on the river all day long floating and fishing, it is easy to forget about the suns powerful rays. The huge brim on the Aquifer Sombrero keeps the sun off my skin and out of my eyes. I enjoy dunking it in the river on really hot days and let the water evaporate for an extremely nice cooling sensation!
