Coolhead III Zero Booney Hat offers broad sun protection and cooling for hot adventures

What Our Gearhead® Experts Are Saying:


"This hat has been my summer savior on long hikes. The wide brim and cooling tech make it perfect for keeping comfortable and protected, even on the hottest days."


We rely on the Coolhead III Zero Booney Hat to keep us cool and protected during sun-soaked adventures. Designed with Omni-Shade™ Broad Spectrum UPF 50, this booney shields us from harmful UVA and UVB rays, allowing us to focus on the journey instead of worrying about the sun. The sweat-activated Omni-Freeze™ Zero technology helps regulate our temperature, while the moisture-wicking Omni-Wick™ fabric keeps us dry and comfortable, even during intense activity. A packable cape and an adjustable drawcord toggle enhance its versatility, making it our go-to hat for hiking, fishing, and exploring under the sun.

Its huge, way bigger than the photo

[This review was collected as part of a promotion.] Its way biger than what it looks on the picture, its like 3 inches wide to each side, its like wearing an umbrella, but it acomplished wgat it promaises, it covers the sun has a cover for the neck so it protects from the sun really well its not the most stylished but is really good quality

Making My Dermatologist Happy

[This review was collected as part of a promotion.] I've been using a Columbia bora-bora booney hat for a couple of years and bought the Coolhead III Zero as an upgrade. The brim is a bit wider and seems a little more structured (less "floppy"). I haven't had a chance to test the cooling effect of the omni-freeze materials yet, but i love the overall fit and the sun coverage.

Floppy hat

I was really looking forward to this being my new sun hat. However, the brim is so floppy. The lightest of breezes flips up the brim. It just isn't sturdy
