First of all I'm 6'1" and 170-180 pounds and the large size fits me very well. I have an elite jacket but this winter has been very cold so I chose this jacket instead of wearing multiple layers. The jacket keeps me very warm; It was 30 this morning and all I needed was my regular shirt in and all. When it's 50 outside, the jacket gets too warm and I just unzip the front. The quality is excellent and the color is very bright (RED).
