We partner with charities that are close to our hearts to make limited-edition, custom-designed, absurdly soft graphic tees. $15 from each shirt goes back to that organization — this one goes to Sierra Club. Sierra Club is an environmental nonprofit that defends our most precious resources and wild places. We mixed our Signature Re-Spun fabric (you know, the one made from your old tees) with some recycled polyester and sustainable TENCEL™ Lyocell for durability. The result? A low-impact, high-softness tri-blend fabric. Which is exactly what we’re about.
