Basically true to size, but maybe a smidge small. The pattern I ordered, "black" dot (that's really little green dots), isn't the most attractive, but it was the cheapest.
The jacket repels water well, but it's not as warm as I had hoped.. and if I jam myself into it while wearing a hoodie, I'll look like Chris Farley in Tommy Boy.
When washing, there is a specific set of instructions you must follow, including tumble drying on low for 5 minutes to "reactivate"the repellent feature. So be prepared for a jacket that's more high maintenance than a Kardashian.
