The benefits of our fabrics

Fabrics that are 100 per cent biodegradable, made in an innovative and environmentally friendly way as our nature-based production method virtually meets the highest standards of sustainability and quality.

Then, the magic happens. The natural moisture released by the skin, when in contact with the fabric, triggers a simple reaction producing an active exchange between the seaweed extract embedded into the fibers and the skin. The skin absorbs the essential nutrients, which helps the whole body to benefit and to feel good.
