Buck Mason is a modern American Brand founded in 2013 by Sasha Koehn and Erik Allen Ford, who were neighbors in Venice, California. At the heart of everything we do is the laid back California ethos of easy living, quality, and simplicity. We are classic. We look to past icons and interpret them with honesty and loyalty. We also look ahead and understand the modernity of future classics and the responsibility of our place amongst them. We champion anyone striving to be better and are honored when we can be a part of it. We claim simple truths and keep our promises. We truly have our customers’ best interests in mind, knowing damn well the value of a hard-earned dollar. We believe we will never be perfect but know that greatness lies in the search to be so. We make clothes. We love what we do. Initially, they set up shop in a 350 square foot garage off Abbot Kinney Boulevard. Sasha built the website and Erik created the brand’s first collection of jeans and tees. Obsessed with quality, they worked closely with a local family factory to create small batch production runs, crafting each piece using old school manufacturing techniques combined with modern technology. Buck Mason makes fashion less complicated, building each piece to last beyond a single season. Each design is a riff on an iconic American staple, combining to make a useful and effortless wardrobe. Consistency in fit, fabric and quality guide this hands on approach. Much of the product is made in the USA, where you can often find Sasha and Erik on the factory floor.
