The new ethically produced, eco-friendly and sustainably sourced crop tops and bib stocks are made from 93% Tencel and 7% elastane, giving the fabric long lasting softness, a comfortable feel, excellent breathability and extremely good color retention. Tencel is produced using the Lyocell process which changes wood into a textile fiber. It is mainly derived from the Eucalyptus tree, a sustainably sourced raw material and is produced using a closed loop process, keeping the environmental impact of production extremely low and also allowing the production process to be certified as carbon neutral.
