Hiya, thanks for your question! This jacket does not have a temperature rating. In fact, most jackets do not have temperature ratings. This is for several reasons. Mainly, it's because warmth is a subjective thing, unique to each person. Not only that, but there are other factors that can affect a jacket's warmth: wind, humidity, activity level, what else you are wearing, etc.
That said, this jacket is designed for snow sports, like skiing, snowboarding and mountaineering. It will keep you warm if you are participating in winter activities but it is not meant for casual wear.
If you are looking for a casual wear jacket for 0 - 15 degree weather, check out the Marmot Men's Fordham Jacket or the The North Face Men's Tweed Stanwix Jacket.
