Thermae Sauna Hat — 100% Natural Merino Wool
No Toxins. Ever. Most sauna hats are made from synthetic materials that release harmful chemicals when they get hot. Thermae is made from 100% Merino wool — nothing off-gasses, nothing leaches.
Your Hair Stays Protected. The intense heat of a sauna is brutal on hair. Thermae's wool construction shields every strand so your hair never feels the heat.
Stay Longer. Go Deeper. The longer you sweat, the more your body lets go of whatever has been holding you down. Thermae's natural wool insulation keeps your head cool so you can extend your session and let the heat do its full work.

Frequently asked questions
Most sauna hats are made from polyester or acrylic. Synthetic materials that release toxic fumes when exposed to high heat. Thermae is made from 100% natural merino wool. No synthetics, no off-gassing, no compromise.
Merino wool is naturally heat-resistant, breathable, and free from chemical treatments. It regulates head temperature in the sauna without breaking down or releasing harmful compounds the way synthetic fibers do.
Hand wash in cold water with a gentle wool-safe detergent. Lay flat to dry. Do not machine wash or tumble dry.
