100% undyed wool, washed with water only, dense felt, room for long hair, and a brim you can fold: what to look for in a sauna hat.

Everyone tells you to drink your electrolytes and sit on a towel. No one tells you to protect your head, the part taking the most heat in every sauna type: infrared, traditional, steam, even cold plunge. This guide covers why undyed wool sauna hats protect your head and hair, what sauna heat actually does to colored or bleached hair, how often to wash one, and which of the seven natural shades fits your setup. Hand-sculpted in Vilnius, no dyes, no synthetic fiber.
