Thanks for the suggestions, Comms. I have some of the very lightweight nylon pants and shirts for backpacking and casual outdoor use from various makers. By the way, Academy Sports has some really nice models, near copies to Columbia, etc., at very good prices, zip-off or not. I now have enough use on them myself to say they hold up well.

What I need are some in the recent BDU pattern, in khaki, which are issue for the federal agency I work for. Unfortunately, the issue is in poly-cotton, which is still way too hot, heavy and slow drying for me, especially since I know superior fabrics are now available. I even looked into having a half dozen or sets made up for me, without success.
