Thick Wool Felt Sauna Hat, Heat-Protective Cap for Sauna and Bath, One Size, Grey
Thick wool felt that sits loose, so trapped air keeps your head cool.
Details
This thick wool felt sauna hat is shaped to sit loosely on the head rather than grip it. The loose fit is the point: a layer of still air under the felt does the insulating, and wool conducts heat badly, which is why sauna hats are felt, not cotton. One size, in gray.
It hangs on a peg outside the sauna door. It is a heat-protective cap for anyone whose head starts cooking before the rest of them is ready to leave; with the hat on you sit higher and stay longer. Home sauna, spa sauna, and it goes into the bath too. One size, so a couple by the door cover guests. Gray suits pale and dark paneling alike and hides marks.
Dense felt holds its shape dry and traps air when worn, and with no weave there is nothing to fray and no seam to split in the heat. After each session lay it flat to air dry, away from direct heat. Never machine wash it and never wash it warm, because wool felt shrinks and hardens. To freshen it, rinse in cool water, squeeze and dry flat again. Store it dry, not in a damp sauna bag.

Why it earns its place
Loose by design
It sits on the head rather than gripping it, so a layer of still air does the insulating and your scalp stays cooler on the top bench.
Thick wool felt
Wool is a poor conductor of heat, which is the whole reason sauna hats are felt and not cotton.
Soft grey
A plain colour that looks right in a wood-lined sauna and does not show every mark.

In your home
This lives on a peg outside the sauna door, ready for the next session. It is for the person who likes the heat but finds the top of their head cooking before the rest of them is ready to leave; with the hat on, you sit longer and higher.
It suits a home sauna or a spa sauna, and it goes in the bath with you too. One size, so it is easy to keep a couple by the door for guests. The grey sits well against pale and dark panelling alike.
Materials and quality
It is thick wool felt, dense enough to hold its shape when dry and to hold a layer of air when it is on your head. Felt has no weave to fray, so there are no edges to unravel and no seams to split in the heat. The fit is loose on purpose. In the hand it feels heavier than a cap has any right to, which is the felt doing its job.
Care and everyday use
Air dry it flat after every session, out of direct heat. Do not put it in the washing machine and do not wash it warm: wool felt shrinks and hardens. If it needs freshening, rinse it in cool water, squeeze it and lay it flat again to dry. Store it dry, not in a damp sauna bag.
Good to know
Will it fit me?
It is one size and shaped to sit loosely rather than grip, so it fits most heads without a tight band.
Can I wash it?
Not in a machine and not warm. Wool felt shrinks and hardens with heat, so rinse it cool if you must and air dry it flat.
Do I need one for a home sauna?
If the top of your head gets too hot before the rest of you, yes. The felt traps air and keeps your head cooler, so you can stay longer on the top bench.
