Bought this jacket to wear on cold (below freezing) multi-day backpacking trips. I am always cold, but this jacket, when combined with a thermal under layer, kept me toasty in the low 20s/high teens (F). Cinch-able hood kept head and face warm in wind. Performs well in falling snow without a waterproof layer. I am 5’7”, weigh 115 pounds, and the US small is a perfect fit (either with out without additional under-layers).
