Meet your new favorite fabric. It's called doublecloth, a plush cut of cotton made from two double-sided layers that've been loosely woven together to form one ultra-soft layer. To make this shirt, that doublecloth fabric is sturdily sewn into a handsomely practical, long-sleeved field silhouette. In terms of details, you're looking at a classic seven-button placket, two buttoned chest pockets — one with a woven loop for securing your glasses or a pen — and a thick locker loop at the neck for easy hanging. The fabric's made with longevity in mind, so it'll get softer, more faded, and more textured over time.
