Great for sun and rain. Love this hat for kayak fishing.


I got myself this hat to upgrade from my previous sun hat, a columbia in a similar wide brim style. The OR Aquifer Sun Sombrero has a wider brim, and a better overall design with many superior features. First of all, it is not a one size fits all hat, it is sized, but you still have the ability to adjust the size with a tension cord. This was great in unpredictable weather, I could wear the hat on my head and tighten it, or loosen it off to fit over the hood of my jacket to help keep the rain out a bit more. I particularly like the brim of this hat. Not only is it wider than my previous hat, it is shaped at the front to keep the wind gusts from grabbing the brim and flipping the brim up, or knocking the hat off. I also like the chin strap on this hat, it does not bother my ears or face, and is removable, not that I would remove it, as I'd be afraid of losing my hat while fishing. I did get this hat knocked off once, just while on the dock, and it floated long enough for me to rescue it. The foam used in the brim gives it a bit of buoyancy. I'm super impressed with this hat, it was a bit more money, but worth it. I'm pretty sure I will be wearing this style of hat from OR for anything outdoors that involves the possibility of sun or rain.
