T-shirts are quite possibly the single greatest clothing invention of the 20th century. Originally worn only as an undershirt, young guys started sporting them solo in the late 1940s and 1950s. At the time, it was a total rebellion from conformity. Old men and women scowled. Young girls swooned. Then the men’s tank hit the scene, and things really got radical. Cut the sleeves off anything, and you’ve got a recipe for trouble. And trouble we like. Scope our selection of men’s T-shirts and tanks from Volcom, Plan B, DC Shoes and Pearl Izumi, and don’t forget your comb switchblade.
