Marine Layer is an American clothing retailer founded in 2009 by Mike Natenshon and Adam Lynch in San Francisco, California. The company began when Natenshon’s girlfriend threw away his favorite t-shirt, inspiring him to create a brand focused on producing exceptionally soft, casual clothing. Marine Layer is known for its signature fabric blend, made from recycled beechwood and cotton, which undergoes a specialized manufacturing process to achieve its characteristic softness. The company initially gained recognition for its men’s t-shirts but has since expanded its product line to include women’s clothing, accessories, and children’s wear. Marine Layer emphasizes sustainable production practices and maintains a strong commitment to environmental responsibility, including the implementation of their “Re-Spun” initiative, which transforms old t-shirts into new clothing items. Marine Layer operates numerous retail locations across the United States, primarily in coastal cities and urban centers, while maintaining a strong e-commerce presence. The brand’s aesthetic reflects a laid-back, California lifestyle, and its marketing often incorporates humor and casual messaging that resonates with its target demographic of young urban professionals. The company is also known for its micro-modal fabric production and its made-in-California manufacturing approach for many of its products.
