Excellent jacket! Very warm for weight. I stood around (no physical activity) in 40 degree weather with slight wind and was warm. Adding a light rain jacket increases warmth to around 30. Dries quickly too, and the water resistant coating beads up rain.
I usually wear an XL, but could probably fit in a large in this jacket. My XL does allow for more base layers .
