This is the vegetal wool you were looking for.
PYRATEX® tropic fabrics are isolating, breathable and quick drying. The moisture-managing knit fabrics are made from kapok flowers which grow naturally in tropical forests without the need of irrigation, pesticides or fertilizers.
The fiber is picked from the pod as a fiber form already, meaning no extra energy or water is applied in the fiber processing leaving the tree untouched and continuing to regenerate the ecosystem.
A collaboration with Lenzing, Flocus, Marchi & Fildi and Studio MLR.
