From Under Armour, this hat was designed to keep your head cool by dumping excess heat through special vents that allow hot air out, but are small enough that the sun's rays aren't an issue.

Best cap I owned
Absolutely — here’s a polished positive review you can post:
I’m really impressed with the Under Armour Uncrushable Hat. It’s lightweight, comfortable, and holds its shape extremely well even after being packed or tossed in a bag. That makes it perfect for travel, the gym, or everyday wear.
The fit is comfortable, the material feels durable, and it has the quality I expect from Under Armour. I especially like that I don’t have to worry about the hat getting bent or ruined when I pack it.
Overall, this is a great-looking, practical hat that’s easy to take anywhere. Definitely recommended!

Good fit on hard to find low profile hat.
Please make this in dark navy blue so I can wear it at work. Good fit and looks neat. Hard to find low profile hats anymore. I have large head and went with L-XL.

The hat fits great and I love the stretchy material. It even helps me stay cool when it's hot outside.

Comfortable fit
Wore this the first day I got it to the golf course on an 85 degree day. It was light enough I didn’t even break a sweat. Even better is the fit. Usually flex fit hats have sizes S/M or L/XL which are either to small or too big for me. The M/L is a perfect fit.

Not my favorite hat but very good. Great for summer and golf to have some venting. Wears well to not show the sweat
