Richard,
Good reasoning. The Techron won't stick to NikWax treated material. I withdraw my 2-step treatment recommendation with NikWax.

So I'd just go with Techron alone or, better, so I've heard, is Revivex from WL Gore.

I do know some bicycling wind jacket/shirts are made with highly water repellant fabrics like you mentioned, with no DWR surface treatment. (Nextec?)

I tried waterproofing the seams of a windshirt I got on closeout. It worked fairly well but it did add a fair amount of weight to the shirt. Also, I didn't find the jacket to be nearly as "breathable". I still like the DriDucks jacket (or just getting wet if it's a warm rain).

I'll add on edit that the DriDucks jacket IS a windproof jacket... said another way...

Windproofing a rain jacket? vs Waterproofing a windshirt? (hehe)

It's now possible to come in under 10 oz., carrying both a dedicated windshirt and a dedicated rain jacket. I think this fact alone derails serious consideration of trying to H2O proof a windshirt. For now...

But just wait for the next generation of DWR currently under development----all the water repellancy that you initially get from today's best DWR but a far more durable and abrasion resistant treatment than is currently available.

Based on the experience that some of you have with the Featherlite H2O, could it sereve double-duty as a windshirt and sole rain jacket for summere use? If yes to summer use, any sense how much futher into fall/spring it could comfortably used in this fashion? Generally would have light/mid weight base later beneath and if necessary, insulating layer as well. Feedback greatly appreciated.
