One of the most useful items that come's handy when planning a long hike in hot and sultry weather is Columbia's best-selling option- Coolhead Cachalot. Made with moisture wicking UV protection properties, the cap does a fantastic job at keeping you cool and dry even when the sun is blazing. Omni Freeze reacts with your sweat to provide instant and prolonged cooling. The long back protects your ears and neck from excessive sunburn, light rain and wind. The cap is one-size-fits-all, but the draw-cord and toggle at the back secures the adjustment and prevent it from flying off on windy days. Coolhead Cachalot can also meet your stylish needs with its earthen colors that match the rest of your hiking gear wonderfully.
