This article is knitted from 100% organic cotton yarn. The yarn comes from the company Trifitrofa in portugal and is processed by our knitting supplier on flat knitting machines. Our organic cotton prohibits the use of chemical fertilizers, genetically modified crops, defoliants and synthetic pesticides. Organic cotton uses less water than conventional cotton. it has a very low allergy potential and is therefore gentle on the skin. it is not a blended fabric and therefore easy to recycle.
