I tried on the Define Jacket a couple of weeks ago and really liked it. I believe it is an updated version of the classic Shape Up Jacket. It is made of luon and is meant to fit close to the body. To me, the best design feature is the back vent. I just love the look of this; it just makes your waist look so small. There is mesh underneath for breathability.
PS - I also liked the Off to Class Jacket and will post as soon as I get a photo and product info.
