The Research Shirt is built from a lofty, heavyweight brushed cotton flannel, offering warmth and comfort across varied environments. A ripstop-paneled chest pocket adds durability where it counts, while two large chest pockets, an accessories loop, and a snap-closure left pocket provide practical storage for gear and tools. Cut in a relaxed fit with a flat hem and clean-finish interior seams, it moves naturally between rugged outdoor tasks and everyday settings.
