Our High Caliber Heavyweight Cotton Insulated Shirt Jacket features polyfill insulation that packs the heat without the bulk. Strategically placed layers of lightly waxed cotton suede at the shoulders, elbows, collar, and pocket flaps add durability where it matters most, while still delivering all-day comfort. We’ve added a pencil slot pocket for quick access and a locker loop for easy hanging. With poly-lined sleeves, slipping this jacket on and off is a breeze, making it your reliable choice for those frosty mornings and chilly days.
