I love my Rivers West, and until someone comes up with something new and better, its all the raingear I'll own.
Its the only thing besides the old rubber pickle suits that's truely water PROOF. The vents are a very nice feature, because they don't breath and you will get hot in them, but you'll stay dry.
Real bonus it is is super quiet too. No more crinkley gore tex, and it doesn't tear either.
