This parka will really keep you warm. Proper layering in temperatures around freezing will be important and I haven't been in really cold temps yet, but I expect to be comfortable in it (and I'm ALWAYS cold.) I originally bought a MH Chillwave but the sleeves on it were too short. The sleeves on the Frost Line are plenty long (I bought a large and wear 35/36" sleeve in dress shirts.) I do wish it had an external chest pocket. Also, unfortunately this parka is made in China, which has already blown my New Year's resolution to avoid buying Chinese products. I guess warmth trumps principles this time. Very light weight, great down loft, great parka!
