All Mammut products I have used are excellent - in fact, about the best I know. This Polar-Tec Light mid-layer (but it can be used as a thermal first layer as well) is just as excellent, very light, very comfortable, moisture-wicking, warm - and cheerful-looking with the combination red/raspberry/orange at the zipper, cuffs and hem. I ordered one first, to make sure the size was right, then ordered a second. If you are not very tall, they will run a bit long; I had to shorten mine, but it was definitely worth the work! And I will definitely return to CampSaver, I was very happy with their service.
