Founded in 2010, Philadelphia-based United By Blue is already making waves with its efforts toward ocean conservations, along with stylish, functional apparel made with premium materials. Case in point: the Ultimate American Jacket. The garment lives up to its name with incredibly warm bison fill insulation, and a shell that’s both breathable and entirely waterproof. Details include taped seams, a removable vest for extra warmth, and a total of 14 pockets to store your accessories and gear. Best of all, the jacket is backed with a lifetime guarantee.
