Resurrecting thread to add I just took delivery of a Patagonia Alpine Houdini (finally able to get one at a price I was willing to pay).

Since the predicted high today is [checks] 86 I won't be testing its waterproof-breathenicity at the moment. (Waterproof, yes; breathable, who knows?) I can still verify it's as light and compact as they claim (spec says 6.6 oz) and roomy enough to layer atop insulation.

Having owned two-pound rain shells, this is quite another thing entirely. At last I have a rain jacket I can always keep in an outside pack pocket without taking up all the space.

Cheers,
