I have been very impressed with the Kavu Synthetic Strapvisor so far. I have been using it for a little over a year now, and it has taken some serious abuse! It shows no signs of wear and tear, and the color is till the same as when I bought it, no fading!
Pro: Stitching is very solid, super easy to adjust when the wind picks up, dries very quickly, and there is a d-ring on the back so you can clip it to your pack or in my situation, a pfd!
Con: The bill does not really hold its shape that well, but some could look at this as a plus, for ease of stuffing in a pack.
