Last winter I climbed a lot in the Hymir smock, made out of the same Neoshell as the Asmund, and didn't find I did get particularly cold in it. And with the Jöttnar Bergelmir, being a thicker face fabric, I've never noticed it being a big issue at all, so although spotting the wind permeability of NeoShell seems quite a personal thing (and I do notice it! For others it doesn't seem to bother them), I wouldn't write off the membrane for winter climbing. Both the Bergelmir and the Marmot Nabu which I reviewed a few years back

> All in all neoshell is a material which doesn't do anything particularly well.
Again, not my conclusion but it is always really interesting to hear what others think. Have you tried the newest Goretex Pro? My understanding is that they made that air permeable too, in order to compete with NeoShell on breathability. I wonder if anyone is finding that not windproof enough.
