Some things get better with age, like whiskey, jazz and indigo dye. Going on a cool 6,000 years, indigo dye is known for its rich hue and Clint Eastwood-like ageing process. Our mid-weight Indigo Flannel Slim Shirt builds on that tradition with 100% organic cotton, updated with a modern slim fit and chambray lining at cuffs and pockets. The more you wear it, the more youll dig it. When you sit on your porch years from now, youll think, Yep, I still got it.
