The guys at Palmer Trading Company have created a refined shirt-jac with Johnson Woolen Mills; The General Sherman in heavy wool. The site shows it in grey herringbone, black and blue; there is a red possibly too. Nails. More here.
We built the General Sherman shirt to be slim fitting. Simple enough to be worn over a t-shirt and heavy enough provide the comfort and warmth of New England outerwear. [$235]
