This is a recent acquisition, so I don't yet know how it fares in the wash (hence the 4-star rating). However, it is amazingly warm considering how lightweight it is, and very soft. I wear size 8-10 and the medium it fits easily over a long-sleeved shirt or thin sweater, with a little bit of room to spare. It will be an excellent travel piece as it doesn't take up much space and weighs next to nothing. I like the little pocket on the sleeve to use for keys if I'm out walking. If it holds up in the wash, I'll order more.
Bought it for my wife. She loves it. Very soft and comfortable. Be aware, it is quite thin and light (it's a cool summer/early fall jacket). Haven't had it long enough to discuss durability, but the climate this is intended for is very short in our area, so I expect this to last a long time.
Liked the fit and light warmth for here in the south. Color was not anything like what was pictured on the web site, though. Disappointed in the expected color, but kept it anyway.
