Our Signature Tri-Blend fabric plus a custom graphic with our coordinates on it, in case you get lost in the woods. Our signature Tri-Blend Fabric: Tri, for three, different fabrics blended together. 50% Polyester + 38% Cotton + 12% Rayon = Tri-blend. Voilà! Colin is 6'1" and in case you were jealous about how nice he looks in our tees....just know he puts them on in a really weird way. Sorry Colin, you know it's true.
