In reply to squicky: Patagonia is well into the hybrids - mixing materials this year. I have a RAB shadow hoody which is made of the same windpro material - but ALL of it is. It is excellent material - super breathable - like normal fleece, but very wind resistant. Haven't tried the Piton, but I do wonder how much difference the rather small amount of windpro makes? Would be interested to hear what other say
I think there is a video of their "Ambassadors" raving about it on the Patagonia site, but then they would, wouldn't they?
