Our mark

The ROSISU symbol combines the four elements, fire, water, earth, and air, into a single interlocked form. In alchemical tradition, these are the forces behind all transformation. In the sauna, they're literal: fire heats the stones, water becomes steam, the earth grounds your body, and air carries the breath. Every session is elemental.

Field to Felt

ROSISU works with small producers in the United States to craft high-quality felt for sauna use. Every piece is made in the USA with a focus on durability, performance, and long-term use.

FAQ

Why use wool in a sauna?

Wool naturally regulates temperature, insulates against extreme heat, and manages moisture, helping you stay comfortable during your sauna sessions.

Will wool get too hot in high temperatures?

No. Wool acts as an insulator, protecting your body from excessive surface heat while allowing airflow for comfort.

How does wool handle sweat and moisture?

Wool fibers wick moisture away from the skin without feeling wet, helping maintain comfort during and after your session.

Is wool suitable for shared sauna use?

Yes. Wool naturally resists odor and holds up well in high‑heat environments, making it ideal for repeated use, including shared sauna spaces.

How often should I clean my sauna gear?

Wool requires less frequent washing than other materials. In most cases, airing out your gear between sessions is sufficient.

How long will wool sauna gear last?

With proper care, wool felt is highly durable and designed for long-term use, even with frequent sauna sessions.

Will the wool lose its shape over time?

Wool felt holds its shape well with proper care. Like any natural fiber, it may soften and relax a little over time, and reshaping it while damp after each session helps. 

Is wool a sustainable material?

Wool is a natural, renewable fiber known for its durability and long lifespan, reducing the need for frequent replacement.
