Audre L.wrote a review of Arc'teryx Atom LT Jacket - Women's on October 27, 2012
-Runs snug in the armpits
-Surprisingly warm for how light it is
-Will be good for travel
-I often wear this under a trench coat on cold rainy days to work to keep me warm but look professional outwardly
I would recommend this jacket! I'm 5'3'' 120lbs, and got a size small. Fits perfectly except for the snug armpits - but maybe they do that to keep it looking slim for layering. It's not so snug where it's uncomfortable - just takes getting used to.
