The first lite stuff is awesome, but very expensive. What are your requirements for rain gear? Do you want the best you can get? Do you want to stay dry at all costs sacrificing some breathability etc? Is price a concern?
For the best rain gear you can get to prevent you from getting wet I like Frogg Toggs honestly. That stuff just works. It doesn't breath very well, but if you want to stay 100% dry and not spend a fortune it's awesome.
I have been using first light rain gear for four years now. The pit zips in the jacket help keep me dryer. The waist cinch is a little uncomfortable for me. I like the pants and the jacket very much. They have held up well for the last four years during elk and deer hunting. I normally Hunt two weeks in September, the last week of November and most of December. They have held up well, but they are fairly noisy.
