Plastic swimwear doesn't belong in the sauna.

Most swimming costumes are made from polyester, nylon and synthetic dyes. These materials contain chemicals like Bisphenol A and PFAS, which research has linked to hormonal disruption, reduced fertility, and certain cancers.

Once we learned that, it's not something we could forget.

Being long-time sauna lovers, we believe the sauna is a place to escape the modern world, not absorb more of it. With hopes of one day starting a family of our own, we couldn't accept that there weren't any healthy options.

So we decided to build something better. Garments made from 100% natural materials, coloured with natural dyes. Starting with swimwear and a cowboy sauna hat made from wool.

Why a cowboy hat, we hear you ask? Because being healthy doesn't need to be boring.

If you've found us, welcome.

The breath of steam that lifts off hot stones when water meets fire. The soul of the sauna. And the place every löyl piece begins.
