Patagonia's Forge Mark Responsible Tee is made from 100% recycled fabric and has taken its inspiration from Yvon Chouinard's blacksmith store. The design is from Patagonia's own roots where Yvon forged the pitons (in his blacksmith store) that made climbing Yosemite's big wall possible. The letter styling on the Tee originates from the stamps on Chouinard's first climbing pieces. This versatile classic crewneck can be worn on its own, or layered, and is a great everyday Tee with a story. Features Patagonia's first carbon-neutral T-shirt made from 100% recycled fabrics. Classic crewneck. Rib-knit at neckline and taped shoulder seams for comfort and durability. Straight hem. Fair Trade Certified sewn. Claimed Weight: 213g Materials: 5.6oz 50% recycled cotton/ 50% post consumer recycled polyester jersey.
