Bought this jacket for my girlfriend, fits perfectly. Alpinestars is definitely THE brand to buy for slim/athletic people. Size chart was spot on (except for the "waist" measure where it showed it should have been too small, but it's actually perfect). Build quality of the jacket is really nice and vented panels really does the job on hotter days. It's the second jacket i buy, i also have an Astar 1pc track suit and will most likely buy again if they keep their good price/quality ratio.
