First off, the quality of their shirts say it all. Softness, fade resistance, durability. Then, as if that wasn't enough, an artist pours their infinitely passionate, and beautiful energy into their artwork, which then resonates with me on a fundamental level.AND THEN, as if THAT wasn't enough, they make underwear and undershirts of the same quality material. I AM A FAN OF THIS COMPANY AND THEIR MISSION. My goal is to own one shirt of each they have produced. And their nut huggers and undershirts. HIGHLY RECOMMENDED
