Designed for those who don't stop in the heat, the Coolhead™ Zero IV Hat combines Columbia's most advanced cooling and sun protection technologies, making it ideal for fishing, hiking or long expeditions in hot and humid conditions.

Main product features:

• Omni-Freeze ZERO™: Revolutionary cooling technology that activates when sweat comes in contact. Blue circles in the fabric lower the temperature of the material when wet, giving you an immediate and long-lasting feeling of freshness.
• Omni-Shade™ Broad Spectrum UPF 50: Premium sun protection that blocks a broad spectrum of harmful UVA and UVB rays, protecting your skin from burns and long-term damage.
• Omni-Wick™: Technology that effectively wicks moisture away from the skin to the surface of the fabric, where it quickly evaporates, ensuring you stay dry and comfortable.
• Adjustable fit: The hat is equipped with an adjustable drawstring with a tensioner at the back of the head and a chin strap that ensures the hat stays in place even in windy weather.
• Breathability: Integrated mesh panels allow constant airflow, which further helps to cool the head during intense activity.
• Flexible brim: The wide brim provides plenty of shade for your face and neck, while being soft enough to easily fold and store the hat.
