Here at Mad Gringo, we take the theory of evolution one step further, calling it Gringolution. Gringolution presents mankind’s final step in the evolutionary process – the fully developed man of leisure. You can see him right there on the front of this tee. He’s chucked his office chair for a tropical drink and a pair of MG’s Khakis Now you can join the Gringolution. Just wear this tee under your dress shirt whenever you head into work, safe in the knowledge that you’re taking the final step in an ages old process. And flash it to your coworkers, if for no other reason than to inspire their jealousy.
