Here in El Paso, it doesn't get really cold except in the early morning. During that time period the jacket keeps me warm and toasty. I also use it when riding my motorcycle. The cold air cannot get through, and it is nice and light. It is an awesome jacket.
I am a true beleaver in this jacket. When I went to do some errands the temperature was about 9 above zero in January. A lot of jackets you can feel the cold through the back panel. I did not feel any cold what so ever though this jacket. I hope this jacket lasts me the rest of my life.
I bought this jacket for my husband. He thinks it is the best jacket he has ever owned! It is warm, great for shoveling snow as it keeps you dry. He just loves the jacket.
