Great thanks for the explanation. Sounds like it would work as a MTB jacket but not as a dual purpose for going on hikes, etc. I have a Sombrio Vapour jacket right now, which they claim is 20,000mm rating in terms of breathability. But it's useless when it starts raining. Wets fully through in 20 minutes and takes forever to dry. But doesn't overheat when I'm pedalling. I use it when it gets cold in the fall but still in search of something for when it's likely going to rain.
