Why do winter outdoor headbands leave the crown open and only wrap widely around the ears and forehead?
When moving your body outdoors in cold weather, a hat that covers your entire head easily traps sweat. This question aims to determine how an open-top headband maintains body temperature in cold winds.
It is to manage body temperature by cooling excessive heat, keeping the heat-accumulating crown open while widely wrapping and blocking the ears and forehead that get cold from the wind.
The crown is left open, and the ears and forehead are widely wrapped. When running or hiking in cold air, your skin feels chilly, but hot sweat quickly builds up on your head. Considering these conflicting physical reactions, the Nordic Headband by ostrya widely wraps around the forehead and the circumference of the ears while leaving the top of the head pleasantly open[1][2].
A generous circumference wraps snugly around the forehead and ears, which directly face the cold wind, relieving the chilling sensation[3]. Meanwhile, at the top of the head where heat gathers, warm air and sweat escape outside without lingering, helping to keep the body from overheating[4]. Without the hassle of taking a hat on and off, it reduces the chill caused by cooling sweat, allowing you to continue moving while properly maintaining your temperature even in the cold.

The specific fabric composition and washing instructions used for the Nordic Headband have not yet been confirmed.
