ok so ill give you a review of MY suit from this year without responding to anything anyone else has said
I mainly ski in tahoe and mammoth, so when i have skiied pow this season it has been VERY wet and heavy. So far my waterproofing has been average, the day when it rained i got stuck on a chairlift in the rain for 10 minutes and when i got back down to the bottom of the run the suit was COMPLETELY soaked ONLY ON THE OUTSIDE (minus the butt, but that cant be helped when your sitting in a puddle of water), the inside of the suit (minus the butt) was very dry
on days when it is just snowing but is not raining the waterproofing holds up for me very well, sheds the snow that has melted and snow that lands on the suit never goes through the first layer, that being said, the cuffs of my pants do become EXCESSIVELY wet to the point that the water goes through to my boots/the top of my socks (although this could be due to the small rips i have from my edges cutting them) when skiing in slush/ very wet powder
contrary to belief by many previous posters in this thread, there are few "leak" spots, especially in the zip off sleeves portion of the jacket, fd did a moderate-good job at covering those up, the only complaint i have is that my zipper does not touch the starting point, leaving a dime sized hole underneith my armpit which sometimes, when i have my arms up, not stuck to my body ect. also the pants (minus the cuffs) and the jacket stay waterproof very well, and the jacket is not "single stitch" on my jacket it is stitched many times
sparknotes: FD is waterproof unless you are skiing in rain/ shin deep slush/ superwet pow
