I got this jacket years ago when it first came out & we've been through snow storms and hurricanes. Only now is the DWR starting to show signs of wear around the cuffs and shoulders. The H2No technology is excellent; waterproof, breathable & does a great job of blocking the wind.
My only gripe is the slight bulkiness of the jacket. If you have a silm build you might want to size down. But for those with broad shoulders/torsos, your upper half is going to look ever slightly buffer because you'll probably have to go with your normal sizing for fear of it being too tight if you down-size. And if you're like me, who's vertically challenged (5'4) and broad shouldered, order the XS, look like michelin tire man and love the jacket =] because it's excellent at what it does.
Moral of the story: Make sure you try it on in-store not only to find the right sizing, but also to determine if you like the slight bulk this jacket has.
