Are you looking for low flammability and/or no melting for use near open fire? Â Otherwise, I’m not sure the reason for cotton other than sustainability (though nowadays, a lot of regular cotton grown involves a lot of heavy duty pesticides, and only organic cotton might be considered more truly sustainable)?
I’ll just repeat what I recently said on another thread. Â I really like the 1 oz/yd2 Robic nylon on Ripstop by the Roll’s site. Near ideal air porosity (“breathability”) IF you’re going to use it while active, and very tough for it’s weight. Â But like any synthetic besides kevlar and nomex, won’t do very well in close quarters with open fires and sparks. Â If that is part of the equation, wear your cashmere shirt over the windparka.
If I recollect correctly, I thought I remember seeing a comment where you said that the winters in your area tend to be on the wetter side? Â Cotton anoraks etc, excel more in very cold and dry conditions.
If you can find EPIC fabric that is relatively lightweight and has good air porosity–that’s also a good option. Â I’ve looked for said fabrics and have had a hard time finding them. Â The EPIC that I have is heavy and very low air porosity. Â I can only use it on my lower legs–I velcro it to much more breathable shorts. Â Good for snow, light rain, freezing rain, etc. (n combo with an over sized windjacket for the former and a poncho for the latter).
