great quality, nice warm lining. Size small was quite long...I would estimate the sizing as a 40 chest in a small and then super long...sleeves were normal lengthI bought this as a casual jacket since I don’t get overly cold. In 32 degree weather it’s more then enough for me. I’m 6’2 and 260 and bought a XXL and it fits perfect for me.Absolutely love this CPO shirt. This jacket is all wool, 100 pct., with lining. Pockets good and deep. Put this on and you just feel you're wearing quality, cotton can't stand up to it, polyester is just a joke. I understand that not everyone can afford it, but if you can, buy it!Great fit. Very warm. Worth the money.First Pendleton, big and heavy as expected, don’t worry about being too big for it. Classy hoodlum apparelComfortable, warm yet light, with excellent style. I'd rather spend a bit more for something that will last a long time.Because this shirt jacket is quilted, it`s very warm and comfortable. This is the Shirt Jacket. I love it !!Perfect fit like a glove .I live in this thing now !!My new favorite CPO.Thanks amazon .
