FAQ

What are wood fibers?

What are wood fibers?
Wood fibers such as Modal or Lyocell are obtained from sustainable wood, such as beech or eucalyptus. They are as soft as silk, significantly more breathable than performance fabrics, and naturally biodegradable.

How are wood fibers produced?
In a closed-loop process, pulp is extracted from wood and processed into fine fibers – with virtually no waste, using recycled water, and without microplastics. Sustainable from source to shirt.

What are the advantages of wood fibers over polyester?
Polyester is plastic – it traps heat and moisture, retains odor, and feels artificial. Wood fibers, on the other hand, are cooling, odorless, and pleasant on the skin. They wick away moisture effectively and dry in a flash. Noticeably better – all day long.

What are the advantages of wood fibers over cotton?
Wood fibers are lighter, softer, and dry faster than cotton. They also use significantly less water in production, thus protecting the environment.
