The Fair Trade bib stocks are ethically produced, eco-friendly, and sustainably sourced for ultimate comfort. They're made from 93% Tencel and 7% elastane giving them long lasting softness, a comfortable feel, excellent breathability, and extremely good color retention. And that's not all! The Tencel fiber used is mainly derived from the Eucalyptus tree and produced using the Lyocell process. That means it's sustainably sourced and produced with a low environmental impact, all while being certified as carbon neutral - so you can shop guilt-free.
