Brian A Q.wrote a review of Outdoor Research Bugout Brim Hat - Men's on August 4, 2016
Familiarity: I've put it through the wringer
Fit: True to size
Got this prior to a week long trip to Yellowstone. It was summer in Yellowstone with temps in the mid 80's to lower 90's. The trip included several long day hikes. The fabric and mesh were highly breathable. The one time I did sweat (hottest day) the fabric dried quickly. The insect shield is definitely worth it. The last thing you want in the middle of a 1200 ft ascent are gnats and flies in your face. My wife's hat did not contain the insect guard much to her dismay. There was a noticeable difference between the two hats in this regard. The hat provided excellent sun protection, which was a big plus given the higher UV exposure. This is another great product by OR and I highly recommend it.
