My 2 cents: I would not purchase any of the 100% cotton styles, which is all they used to make. Stick to the cotton-synthetic blends. Or the 100% nylon, if your tastes run that way (mine don't; fire...).

I'll re-state what I've said before: real-world practical, my experiences in HARD use in difficult weather, no outer layer clothing performs as well as Quarpel treated NyCo. There simply is nothing that touches it. The best Quarpel treated poly-cotton fabrics are second - almost as good, but not quite as good. There are plenty of lesser poly-cotton blends out there as well... although any of those are better than plain cotton.

NyCo is expensive and hard to find outside of specific US Military clothing items, although for the life of me I don't understand why it costs so much more than Cotton-poly. Used to be civvies available - any one remember "Mountain cloth" or "Ramar (sp) cloth" or "60/40" cloth? Size of market/demand? Dunno. FWIW, currently available NyCo seems to have settled on a 50-50 blend and I cannot tell any difference between that and 60-40.

Stay away from 100% short staple cotton clothing items. (Long staple, or Egyptian, cotton can be a different matter - up to a point. The label will brag if it's long staple cotton...)

Randy may chime in about Filson now, but that stuff is so heavily treated that it oughta be classified as a blend, LoL - WaCo (Wax-Cotton). Aquired taste, in any event.
