In August of 2014 my sister purchased some Frogg raingear for her trip.  It seems very light and felt like paper.  It didn't rain much during our trip so I have no comment on how it performed in the rain.  But we took a bathroom break and she proceeded to put a hole in the jacket when she came in contact with some dry branches.  I don't think Frogg rain gear would hold up to hard use.

"Cliff Jacobson mentions using 2 rain jackets at times, one under his pfd and if necessary, one over. ugh. rambling on..."

I can put my rain parka on over my PFD, and just barely catch the bottom of the zipper and the first snap.  that works well when you are out in the middle of a lake in the wind and don't want to take your PFD off to put the rain gear on - also give a lot of venting that way - especially nice when you get those on and off and on again rain days - maybe something to consider when you buy your rain jacket.

I have lots of different rain gear - as far as rain pants go, I have an old pair of Red Ledge Thunderlight full zip that I like better than my Marmot Precip pants or my REI rain pants - Red Ledge may be a better option than Frogg Togs with a  middle of the road price.
