Columbia Coolhead Zero IV Booney Hat - Ancient Fossil

Lightweight travel hat in Ancient Fossil color, equipped with a wide brim offering protection against harmful UV rays. Distinguished by an extra neck flap at the rear, this model is ideal for hiking, daily strolls, or traveling in hot climates.

Features integrated Omni-Freeze Zero cooling technology, employing special fibers within the fabric to absorb moisture and accelerate evaporation, ensuring a cool and fresh feel even during strenuous activities in elevated temperatures.

Durable nylon, drawcord with stopper

Constructed entirely from abrasion-resistant nylon, the model offers both durability and a lightweight feel. The quick-drying properties of the material provide enhanced comfort in warm conditions. An adjustable drawcord with a stopper is incorporated, enabling precise length customization.

active cooling, moisture-wicking, and UV protection

Modern Columbia brand technologies have been applied to the hat, significantly improving both comfort and usability in demanding conditions:

  • Omni-Shade Broad Spectrum UPF 50: The fabric offers outstanding protection by blocking the majority of UVA and UVB rays, delivering continuous sun defense at UPF 50 level. This dramatically decreases the possibility of sunburns and skin damage during periods of sunlight exposure.
  • Omni-Freeze Zero: Engineered for active cooling, this sweat-activated technology uses specialized blue rings to boost moisture transport and speed up evaporation, lower the temperature of the material, and deliver a cooling effect in high temperatures.
  • Omni-Wick: Advanced moisture-wicking properties draw sweat away from the skin and transfer it to the outer fabric, allowing for rapid evaporation. This keeps the inner part of the hat dry and helps maintain optimal thermal comfort throughout strenuous activity.

wide brim, neck cover

Fitted with a brim measuring approximately 9 cm in width, the hat offers reliable sun protection for the face. An integrated neck cover provides additional coverage and can be conveniently stowed inside the brim when not required. Engineered for portability, the design allows the hat to be packed away without losing its form, thanks to its soft construction, making it ideal for carrying in a backpack or bag.

    The hat works great during heatwaves – the wide brim effectively shields from the sun, and the head stays cool. The City Grey color is subdued and doesn't resemble a safari hat. Unfortunately, in strong winds, the hat can fall off if you don't use the cord. The light shade of the material also gets dirty easily.
