With a half-zip style, this collar forms a versatile layering option for colder days. Rib-knitted in a soft blend of organic cotton and RWS certified wool, the collar features silver-coloured trims. Organic cotton is cultivated and harvested from non-genetically modified plants, without the use of chemical fertilisers and pesticides. Certified according to the Responsible Wool Standard (CU862581).The wool comes from non-mulesed sheep and is certified according to the Responsible Wool Standard (RWS) - an independent, voluntary standard ensuring that wool from certified farms is properly identified and tracked through all processing stages. The goal of RWS is to protect the sheep that supply the wool and the land on which they graze.
