Because the GOTS classes all animal fibers as “wool” we have to call it wool, but it’s actually 50% Wool, 25% Alpaca and 25% cellulose viscose. A little-known fact is that many viscose fibers are toxic to the environment – the viscose in Eco Tweed is very different! Using the Lyocell process, this viscose is completely benign and free of any toxic chemicals! Because this yarn is woolen spun, more air is trapped alongside the fibres. Woolen spun yarns are loftier, more elastic and lighter in weight, making for a luxuriously soft knit!
