Columbia Coolhead Zero IV Booney

The ultimate hot-day booney hat, featuring built-in cooling technology, broad-spectrum sun protection, wicking power, and an optional cape for extra neck coverage. Columbia offers this hat in multiple colors. One size.

• OMNI-SHADE — BROAD SPECTRUM: Ultimate protection in moderate to extreme sunlight with superior protection against sunburn. More effective on covered areas than sunscreen with more protection against the broad spectrum of harmful UVA and UVB sun rays.
• OMNI-FREEZE — ZERO: For heat and humidity, with activity in extreme conditions. Blue rings react with sweat to lower the temperature of the fabric so you feel cooler, while the accelerated wicking process keeps you dry and provides next-to-skin comfort.
• OMNI-WICK: Moisture-wicking technology for the outdoors. Omni-Wick pulls moisture from the skin into the fabric where it spreads across the surface to accelerate evaporation—for fast drying, enhanced next-to-skin comfort.
• ALWAYS SUNNY: This hat is loaded with tech to keep you cool and dry, and has a packable cape for extra coverage from harsh rays.
• BUILT TO LAST: Columbia’s attention to detail is what sets our apparel apart. Specifying only the highest quality materials, expert stitching, and craftsmanship. This is a long-lasting garment you will enjoy for seasons to come.
