- We made our best-selling Transitional Flannel even warmer for our friends in cold places. - We paired a ridiculously soft 5 oz organic cotton flannel outer with a quilted cupro lining and a recycled polyester fill to make a shirt jacket that's light, lofty, and incredibly warm. - Great for layering — throw it on over a tee or add some heavier outerwear on top when the weather gets tough. - Handy pockets on the chest and at side seams. Finished with natural corozo nut buttons.
