Incredibly soft Moisture wicking Allows to stay cool in the heat and stay comfortably warm on colder days Odour resistant These socks are made with care using bamboo fibre and recycled PET bottles polyester processed with ReNEW recycling technology, which allows to use less resources (water, energy, etc.) than production of new polyester out of crude oil and, of course, helps to reduce the amount of plastic waste! Our bamboo yarn is OEKO-TEX 100 certified, which means that the socks are free of harmful chemicals and are completely safe for use. Bamboo can be grown without the use of pesticides, which together with other factors such as fast growing rate (provides the same volume as cotton from only 10% of the land area) and low water consumption makes it a sustainable raw material for textiles.76% Natural Bamboo Viscose certified with OEKO-TEX 21% Recycled Bottles Polyester 3% Elastane
