The Fitz Roy Bison Responsibili-Tee® is made from a comfortable and sturdy 50/50 blend of recycled cotton/postconsumer recycled polyester. The fabric reduces our need for petroleum to make raw materials and cuts landfill and incinerator waste. Patagonia original art is screen-printed using inks that are PVC- and phthalate-free. Taped shoulder seams lend comfort and fit retention. Fair Trade Certified™ sewn.
