GOTS Global Organic Textile Standard: 100% organic Control Union License No CB-CUI-1417137 At West Path, we spent over a year finding a Fair Trade Certified factory that could make this yoga bag, and we're probably the smallest company to ever source from Fair Trade Certified Factories. We think its worth it, and we hope you do too :). Happy Days and Namaste. P.s. for a limited time there will be a free small surprise inside your mat bag (while supplies last), enjoy! :)
