Ergodyne Chill Its 8935CT Cooling Ranger Sun Hat, PVA Cooling Relief, High Visibility, Reflective

This thing works great! Now, some of the reviews state that the sizing is a bit off, runs small. Remember, in order for the cooling material to work you have to wet it, when you do the inner band expands and the hat will fit perfectly as well as keep your head cool. If you put it on dry the inner band contracts a bit making the hat fit snug. Believe me, wet it you’ll love it!

Like wearing a light on your head so you won't get run over. Bright vest and hat, wow what a combination.

Only con I've discovered is that the brim could use a black material on the underside of the brim to cut out glare from sun. The sun comes through the brim and literally glows... I have a khaki bucket hat that has a black under brim and there is no glare at all. Overall this is not a bad hat for the price. I walk in National parks and some of it is side of the roadways, but I also walk at night as it is more convenient for my work schedule. So reflective gear helps me be seen both day and night. Makes my gf worry less.

I was skeptical at first but for less than $20 I decided to give it a try. I ordered the extra large. My fat head measures 23.5". It for perfectly when wet. Dry is uncomfortable because the absorbent head band is very stiff.I do a lot of hiking in the summer near Palm Springs CA. I have to admit it works pretty well. Almost uncomfortably cold at times. I rewet it about every hour. It would probably dry out in 2h here on the dry desert.Only two objections I have is the hat brim, or the flappy sunshade could be a little stiffer. Flaps in a moderate breeze. The 2nd is the color. In the sun it is a blindingly bright iridescent yellow-green. I mean it hurts the eyes to look at it. It's fine for safety I suppose. If you're lost in the desert they'll see you 2 miles away. The color might have more to do with heat reflection. A bright white might be better.

Poor quality, headband too uncomfortable to wear!

Runs small, had to put it on backwards to fit. Said it was xl,xxl.

Ive worn out a few of these over the years... great for summer...Niceley made.... highly visable..i recommend

Lightweight and keeps him cool
