The Carmine Flannel in Coffee by Knickerbocker, NYC. 

Details
The Carmine Shirt combines the refined details of a dress shirt with a relaxed fit and flat-hemmed silhouette more in line with a work shirt. Designed to be worn untucked, it falls just below the belt line for an easy layer that pairs seamlessly with outerwear without the hem extending too far.
