For starters, the jacket surpassed my expectations. Much heavier and more substantial than the "shirt jacket" I thought I would receive. Once you have it on, you feel the weight and thickness, which contribute to the warmth it provides. The natural materials additionally, provide a soft, plush, comfortable feel. Can be worn with a t-shirt, thermal, or sweater as a base-layer showing off its flexibility to be worn for most-any occasion. Provides great breathability with the ability to retain body warmth. Cut, styling, colors, even the zipper is fantastic. Have already received several compliments. Definitely recommend.
