Cashmere dream
Just arrived today. Very soft, light and warm. Fits comfortably without being tight. This hat is really well made and it far exceeds the price point it’s sold at.

Perfection in the form of a hat.
Best hat ever! It’s perfect in every way, fits right to your head like a skully cap should. It’s not too thick or thin for a chilly winter in the mountain forest, I wore it to sleep a few times, doesn’t seem to make me too hot.
