Extreme mid layer jacket

The extreme mid layer jacket checks off every box on my list of desirable characteristics for a winter jacket. I already own plenty of duck down outer shell parkas, but I sought a jacket that will remain warm and keep its shape even after getting damp from sweat or rain. Overall, this extreme jacket was an excellent product purchase that I am very happy with because it fits under all of my outer shell jackets. I highly recommend this product.
