Hello,

I’m not up to speed with the most recent developments in fabrics. I’m looking for a very light high CFM (>35) fabric. Given that requirement I need to balance the weight to fabric-to-fabric abrasion resistance ratio.

Thanks,

Martin

Probably Argon 67 or 90, but not sure what amount of abrasion resistance you need.

The following BPL thread has some good information about comparative breathability of LW fabrics:

I can confirm that the 1 oz HyperD (uncalendered) from RSBTR is quite breathable compared to a couple other LW breathable fabrics. I made some wind pants from this material and they are way too breathable to be considered “wind” pants IMHO.

My own recent experience with a very permeable fabric is that once you get over that 35CFM rating it probably isn’t actually worth wearing such a garment. Mind you the garment I was wearing had a CFM of about 115CFM
