Frequently asked questions
What makes Koriboshi sauna hats different?

Our hats are designed with a clean, minimal aesthetic and made from super-soft, premium cotton. They’re double-layered for extra protection against heat, giving your head and hair better insulation and comfort during hot sessions.

Unlike wool, our premium cotton is non-itchy, vegan-friendly, and much easier to machine wash, making it more hygienic for frequent use.

You can even wet it before your session to help keep your scalp cooler. It’s a practical, low-maintenance option for everyday sauna users.
What's our return policy

We offer a 100% Satisfaction Guarantee. If your Kori Boshi sauna hat doesn’t meet your expectations, you’ll get a full refund—no questions asked, plus free returns.
