Natural evaporation ensures a cool head.
The Cool Cap with XL water reservoir: Up to 5°C cooler than the outside temperature.
Simply soak the 10 x 20cm (3.9" x 7.9") sized fleece inside the cap with water. It stores the cool water and releases it for up to 5 hours for refreshing coolness. It covers the entire crown of the head and not only a narrow band on the edge, as with conventional models. Measurable effect: The temperature under the cap is around 5°C lower than the outside temperature.
The principle has been proven for centuries.
As early as in ancient times, people used moist amphorae to cool food by means of evaporation. The open-pore surface of the clay provided the necessary air circulation. Here, a high-tech fabric with mesh structure performs this function.
The sturdy 8.5cm (3.3") wide brim provides glare-free vision and protects your eyes.
Thanks to the strap with rip-tape fastener at the back, you can adjust the width precisely – from a head size of 54cm (21.3") to 65cm (25.6"). Colour: Blue. 100% polyester. Hand wash only.
