Our verdict

A UPF 50 boonie hat built around wet-and-wring cooling fabric more than the brim itself, best judged by whether that cooling gimmick fits your routine.

Overview

A wide-brim boonie-style sun hat using water and sweat activated cooling fabric, rated UPF 50, with an adjustable neck cord and a single 23-inch circumference sized around a 7 1/2 hat.

The listing pitches it across hiking, fishing, beach and even yard work rather than as fishing gear specifically, so despite sitting in a fishing-hats category it reads as a general outdoor sun hat whose main feature is the cooling fabric rather than the brim style.

  • Wet-to-cool fabric activated by wetting, wringing and waving
  • UPF 50 rating blocks about 98% of UV rays
  • Adjustable neck cord fits a roughly 23-inch circumference
  • Machine washable without losing the cooling technology, per the brand

Who it's for

Works for anyone wanting shade plus an evaporative cooling boost during hot outdoor activity. Not suited to someone who needs a specific hat size rather than one adjustable fit.

Pros and cons

Pros
  • Adjustable neck cord for a secure fit in wind
  • Machine washable without losing the cooling fabric, per the brand
  • UPF 50 rating blocks the bulk of UV exposure
Cons
  • Cooling effect fades after about 2 hours until rewetted
  • Single adjustable circumference rather than sized options

Performance notes

Wetting, wringing and waving the fabric activates the cooling effect, said to bring the hat up to 30 degrees below average body temperature within about a minute and hold that for roughly 2 hours before it needs rewetting.
