Fish,
I had the older version of the Frogg Toggs and I liked them alot. The problem with them was that:
(1) they would melt very easy.
(2) the neck of the jacket didn't fit snug so you'd get rain down the neck
(3) after about a year of FLA rains, they ****** wore down and they developed a leak in the ******. Very embarassing at work....
I've seen new versions that have a heat shield incorporated into the right pants leg to stop that from happening.
I don't believe that they have fixed the broad neck issue, although if you have a full face helmet, it's not that big a deal.
I don't believe that they have fixed the ****** leak problem either, but at $60 per set, you can buy a new set of raingear when needed.
If you don't fight rainy days too often, they will last quite a while. If you have a lot of rainy days, you may need to buy a new set each year.
