Many outdoor clothing brands have essentially this type of jacket in their repertoire, but I went with the Mountain Hardwear Nitrous Jacket because it was on sale and it was black, and they had it in my size. The reason I am not taking it back is it’s stupendously light-only 333g, and just the right warmth for springtime and with the right layering winter tromping. The cut is slim fitting, but not constricting and makes for a sleek silhouette, which is great because of the gossamer thin fabric keeping the down encased. No snagging on stuff when you walk by, emancipating the 800 fill goose down. The nicest touch, common with Mountain hardwear down products is a stuff sack for the jacket. It fits innocuously in the chest pocket, leaving your front paws for the two hand warmer pockets. Incredibly warm for how light it is!
