Purchased this jacket for my husband. Was a little nervous about what size to get him, but the chart mentioned to get one size bigger if unsure and these jackets run large. Decided to get a Medium instead of a normal large, and it was perfect. He wears it with his office attire and it looks slick. It's been raining out here on the east coast and he was just amazed at how the rain just ran off the jacket. I would recommend buying this jacket for those rainy/autumn months. It's not too bulky, either, so you can wear layers for colder weather, as well.
