After trying to make the Marmot Ion work, I gave up (sent it back)and purchased the Houdini. Huge difference...the Houdini breathes quite well. Haven't been in the rain yet, but water from the faucet rolls right off. Seems to be the best of both worlds.

When I received my Ion I was anticipating another excellent Marmot product. It looks great, has a tie for the hood, well made, Quantum Pertex etc. However, both my wife (who has a Houdini) and I tried it and we both were able to create considerable condensation inside. I tried several shirts underneath and only ended up cold, as well as, wet. If you want a very light and water tight jacket that you won't be active in, this may be it.
