Air after use

Hang it on a hook after every session so it can breathe and dry fully.

Every few sessions, rinse in cool water. A little wool wash is optional.

03

Reshape

Gently squeeze out water and reshape the crown and brim by hand.

04

Air dry

Dry on a hook or over a bowl, away from heaters, stoves and harsh sun.

Care FAQ

Care questions.

Full care guide →

Can I put my sauna hat in the washing machine?

No. Agitation and warm water can shrink or misshape wool felt. Hand rinse it in cool water instead.

How often should I wash it?

Rinse it every few sessions, or whenever it feels sweaty. Let it air after every session.

Should I wet my hat before the sauna?

You can. Dampen it with cool water and wring it out for an extra cooling feel. It works dry too.

How should I store it?

Hang it somewhere airy and dry. Avoid sealing it in a bag while damp.

My hat has relaxed a little. Is that normal?

Yes. Felt softens and shapes to your head with wear. Reshape it while damp to keep it looking its best.
