I have had this coat for a couple of weeks now and because my metabolism is on low most of the time I was very much interested in warmth. This jacket is so light weight you'd have a hard time beliveing how warm it is. I got the extra large and there is plenty of room for big sweaters underneath. Nice long sleeves and I especially like the cozy fleece in the pockets wich really keep my hands warm. I tried this out in very cold weather and was shocked that when I walked outside I didn't notice a change in temperature at all, this was a new experience for me. Then after going for my walk I noticed I was cold, but not where the coat was only my legs that weren't covered. For those who run hot, You can open the zipper to cool off a bit. I am very pleased with this coat. Now, does Mountain Hardware have snow pants? I also bought this coat here for a cool $80 less than anywhere else at the time of purchase. Gotta love that!
