OK lets start off with that at the time of this review, it's a $12 hat that in the description states 1 size (fits all) and measurements. I purchased the "Bright Orange" for use for hunting as i like boonie / bucket hats for that purpose. This one truely is Bright Orange (very Fluorescent) to meet or aid in meeting any F. Orange requirements. It will not keep you warm in winter, however when put over a a face mask or "skull cap / beanie" is excellent in keeping snow & rain off your shoulders neck face or sunshine out of your eyes. I usually put a handwarmer between the facemask and the hat to aid in keeping warm, though doing that with this defeats the purpose due to the netting. no big deal there.

However, woodchuck / groundhog hunting in my state requires a solid Fl. Orange hat, and in that capacity this perfect to stay cool and have the head breathe a bit, and also creates plenty of shade due to the large brim (larger than most boonies).

It's very lightweight and of no issue to put in just about any pocket or pack. Head band is a bit of a terrycloth material so that'll help to absorb though maybe not wisk away sweat. The netting helps to cool when there is a cross breeze, and allows heat from your "noggin" to escape.

Beyond the chin strap, there's a little pull tab in the band to help cinch the hat to the head.

That hat isn't waterproof or water resistant (to be expected as it has netting in it) but a quick spray with water repellent found just about anywhere helps as far as wearing and keeping the hat (and head) somewhat dry on drizzly days. Again with the netting you can't expect it to keep you dry.

The chin strap is what it is, just sewn on to the edges of the hat and is adjustable. I don't really use it, but is the only way if you wanted to lift up and secure the sides in an upright position.

I do plan on purchasing a few (in a different color light grey / white / khaki) for summer everyday use as a sunhat that doesn't look too goofy on ones head. Would make an excellent fishing hat too, or for the occasional hiker. Heck....it's perfect for wearing while playing horseshoes, cutting the grass, having a drink on the deck, etc. etc.

I bought this for my husband to wear on our (first) Caribbean cruise. We had read that a hat with a drawstring was a necessity because of the breeze generated when the ship is at sea. We also wanted something that would breathe so that he wouldn't roast. Finally, it needed to be packable. This was exactly what we were looking for. Very good quality at a great price. I have not tried washing it yet, but when it gets dirty, I won't hesitate to throw it into a lingerie bag & throw it in the washer.

Nice, comfortable hat. Love the adjustable strap. Product just a shown. Came earlier than expected. Sweet seller gave me a beautiful bookmark as a gift THANK YOU! Got this hat to wear while on the boat. The vents around the band will help cool my head. Looking forward to wearing it out in the sun.

Bought for husband's two week rafting trip down the Grand Canyon. He said that it was perfect for that kind of trip. Was lightweight, kept the sun off; and bounced back once dry after getting drenched in a big rapid.

It is listed as a "mesh boonie hat". No mesh. Just cotton and polyester. That picture is not a representation of the actual item. I would not have bought it had I known I was going to get a hat that didn't breathe.
