What you leave outside matters as much as what you bring in. The wrong attire can restrict circulation, release chemicals at high temperatures, and undermine the entire point of the session.
Polyester, nylon, PVC — none of these belong in a sauna. At high temperature , synthetic fabrics trap sweat against your skin, restrict evaporation, and some release chemical compounds when heated.
We recommend Merino wool as it regulates temperature, resists odour, and outlasted every synthetic alternative for thousands of years. Beanies protect your hair from heat damage while helping your body regulate temperature through the ritual.
