Very warm and superb for ranch work on this extra cold Winter & I stayed warm at zero degrees F. with a 30 MPH wind while feeding and tending to cattle, and I was only wearing a thermal knit henley long-sleeve shirt under it.  Shell sheds most fluids and particulates very well.  The size Large fits as expected for my 69" and 180 lbs, with room to use the internal adjusting cords for a custom body fit.  Only a few minor complaints:  The threads on the outside buttons are flimsy and come loose.  The snaps on the outside bottom pockets come unsnapped very easily.  The slant zipper chest pocket is located too far back to easily reach without acrobatic moves.  Other than that it is great.
