Hatland Novol Cooldown sun visor

The Novol Cooldown is not only ideal because the visor keeps the sun out of your eyes, but also because the sun visor cools. Your forehead is cooled by means of a removable element. This element should be immersed in cold water for 1 to 2 minutes. After submersion, squeeze out the excess water and replace the element in the sun visor. Then the element cools for 5 to 10 hours.

The Novol Cooldown is made of nylon, which makes the cap quick-drying and very lightweight.
