The PP sauna hat begins with the same commitment as every other PP piece: natural material, correct construction for the purpose, and no synthetic compromise. In the context of a sauna hat, that means 100% natural wool felt — the material that has been used in sauna hats for centuries in Finnish sauna culture because it is, simply, the correct material for the job.

The material. Natural wool felt insulates against heat by trapping air within its fibrous structure — the same property that makes wool effective in cold conditions works equally in heat. In the sauna, the wool felt hat protects the head from the intense heat above the benches, delays the sensation of overheating, and allows longer and more comfortable sauna sessions. Synthetic alternatives — polyester, acrylic felt — do not insulate in the same way and may become uncomfortable at high temperatures.

The construction. Every PP sauna hat is made from natural wool felt without synthetic binders or chemical stiffeners. The shape is maintained by the felt itself — the correct density and thickness of wool felt holds its form through repeated steam and moisture exposure without requiring internal structure. The hat is fully washable and improves in condition with correct care.

The one size. PP sauna hats come in one size, designed to fit comfortably across the range of adult head sizes. The natural wool felt has enough give to accommodate variation while maintaining its shape.

The colours. The PP sauna hat collection is available in a range of natural colourways — from undyed natural wool to the deeper tones that carry the PP palette. Each colourway is the result of natural dyeing processes appropriate for wool.

The care. Hand wash in cool water with a gentle wool-appropriate soap. Reshape while damp. Air dry away from direct heat. Do not tumble dry or place on a heat source to dry — the felt will shrink and distort.
