Heat rises — the air around your head is the hottest in the room. 8 mm of wool felt insulates your head so the heat works on your body instead of your scalp. You stay in longer, your hair is protected, and your ears stop staging protests.

100% natural sheep's wool felt, 8 mm thick, hand-finished with a hand-stitched brim and a loop for hanging. No synthetics, no blends, no plastic.

One size fits 54–61 cm comfortably — that covers almost everyone. The felt also relaxes slightly with use and molds to you. If it truly doesn't fit, we'll happily help you swap it or send it back.

Mostly: air it after sessions. Occasionally: rinse by hand in cool water and dry flat. Never machine wash or tumble dry. Full guide on our care page.

Worldwide. Orders ship within 2–3 business days. Typical delivery: EU 5–10 days, US 7–14 days, rest of world 10–20 days — tracked the whole way, with free shipping on orders over $75.

EU orders ship from within the EU, so there's nothing extra to pay at the door. Parcels dispatched internationally to other regions can attract local import charges that the carrier collects on delivery — if that could apply to your order, we flag it clearly before you pay. No ambushes.

Yes — the Kova Gift Set arrives gift-wrapped in a kraft box with a cream ribbon and a ritual card, and no prices anywhere inside.

If there's ever a quality or craft problem — or a hat arrives wrong or damaged — we make it right: a replacement or a full refund, our cost, no return needed. Just send a photo. That promise runs 60 days from delivery, no forms in triplicate.

Of course. Unworn and within 30 days: swap it for another colorway or take store credit and we'll cover the new hat's shipping — or send it back for a refund with return postage on you. Worn hats we can't re-home, so those aren't refundable, but a genuine quality issue always is.

Email hello@kovasauna.com with your order number. Quality issue or damage: send a photo and we sort it immediately, nothing to ship back. Changed your mind: we'll set up an exchange, store credit, or a refund once the unworn hat is on its way to us.
