Feel the softness of soy fibre and organic cotton This is a high gauge knitted crewneck cardigan made with soy fibre and organic cotton. The knit is lightweight without being see through and is soft and stretchy for the highest comfort. Soy fibre is made from the pulp leftover from processing soybeans into tofu and other items. This material not only turns food waste into a new resource; it's also so incredibly soft and comfortable it's often referred to as "vegetable cashmere".
