Love this cozy coat. It's fleece lined so pretty thick but it breathes terrifically. I was a little wary at first because it doesn't have the features of many other soft shells - pit zips, thumb holes, wrist protectors, etc - but it's really great. I love it for around town as well as hiking, snow shoeing, etc. Size-wise, I'm 5'8" and usually a size 4 but the medium is good on this. I can fit a bunch of layers underneath but it's fine with just a base layer too.
