- Common Question
Why Is The Cooler Beanie Dark Colored?
A common misconception is that white or light-colored fabrics always provide better protection in the sun. While lighter colors generally absorb less solar energy and therefore may remain cooler, dark, tightly woven fabrics typically block more UV radiation and can provide greater UV protection. This is why dermatologists often recommend tightly woven, UV-protective clothing, with darker colors providing an additional advantage in UV absorption.
Ordinarily, the increased absorption of solar radiation can cause dark fabric to become warmer than comparable light-colored fabric. The Cooler Beanie is designed to address this disadvantage through its water-activated cooling technology. Once activated, the cooling layers can maintain temperatures substantially below the surrounding environment—up to 40°F cooler under appropriate conditions—helping keep the head cool even during intense sun exposure.
In this way, the Cooler Beanie combines the UV-blocking advantages of dark fabric with active evaporative cooling, rather than requiring a choice between sun protection and cooling.
