I've thought much about the ideal bushwalking/fly fishing shirt - ie very breathable, but with a reasonable degree of water resistance - such that you could wear it in light to moderate rain, and it would repel the water. Goretex or equivalent woud be too "hot". I wondered about event or epic fabrics, but haven't found a commercially available product. I tried using one of the Nikwax products on a Columbia shirt, but it really wasn't water resistant enough. Likewise scotch guard didn't work.
My Black Diamond winter bivvy bag is made from epic fabric, and I was thinking of cutting it upto make such a shirt. Has anyone any ideas that will save it from destruction....?
