Marco Marco is an American men's underwear, swimwear, and sportswear manufacturer, based out of Southern California, and named after its founder and head-fashion designer, Marco Morante. Marco Marco Underwear is miles from bland and lightyears from boring. To put it simply, the designer’s aesthetic is unconventional, bold – and when see-through materials are thrown into the mix – provocative. But no matter how tempting or suggestive Marco Marco Underwear can be, it never feels full-on erotic. It’s too fun for that. Instead, Marco Marco likes to focus on wild, fashionable design rather than straight sex appeal. The underwear contains eco-friendly features, including bamboo fiber and organic cotton. Their products use "more than 80 percent of U.S. raw materials and manufactures all of its fashionable and durable men's garments in the states."
