Not as bulky as the pictures show. I've recently worn it under a denim jacket for padding while still looking good and it works well. Just ordered another one in plain anthracite. The lining isn't very bulky, but enough to make a difference out of the elements. The sleeves are quilted and not too short or too long. The side pockets are good but not big enough for something like an iPhone. Another review said something about a thin collar, they are right. It's not a very durable shirt collar, but if that suits you then it's ok.
