I live in Florida, where it's incredibly muggy whether raining or not. This jacket can be a little sticky on the worst days, but it's definitely waterproof. Therefore, I don't tend to wear it all day when there are scattered showers... only for downpours. The only change I would make is the zipper: I wish it were two-way. The hips run a little slim, probably under the assumption that Marmot ladies are going to be more of that "athletic" shape- but I'm petite with wide hips. Going up a size to a S would've swallowed my shoulders and bustline. The seaming is flattering and the Army color is classic without making me look like the Gorton's fisherman or a trash bag. ;-)
