It looks and feels great and the lining makes it nice and cozy to wear instead of a heavier jacket. I bought one for my husband and one for myself for Valentine Day.
I gave this and another similar lighweight one to my husband for his b-day Feb.2010. I don't think he's unzipped it to 1) go to work 2) sleep by the fire, 3)eat, 4)play guitar, 5) shovel slush outside , or 6) attend a famous wedding (kidding). A must for those who need the warm, soft lining-- unlined sleeves aren't, but no annoying rubbing on shirtsleeves sliding in. And he looks so snuggly! I'm jealous.
I am a 5'4" female who weighs between 110 and 115 lbs. The small was perfect. It is slightly big, but gives the extra room I wanted.
The jacket is warm, extremely comfortable and looks really nice. I got it to replace a windbreaker and though I haven't tested the weather yet, I expect it will do just fine. Other reviewers have said this item works great.
I got the Mallard Blue which is a really nice color. My youngest son (11) tried it on, and of course it was too big, but I suspect the xsmall would do him just fine. He liked it a lot as well.
