My wife and I didn’t like the Rainshields (Very similar to Frogg Toggs) that we had. We tried pretty hard to like them, and their breathability was amazing. The pants durability was pretty weak. I shredded them fast. I used them for about 300 miles on the AT and Colorado Trail.
However, the real issue was wind. When the wind was going they just didn’t offer the protect a nylon-laminated gortex jacket does. They fit so poorly that the whipping around really annoyed us. And a good fitting hood is important to us in the wind.
In the end, I’d say they are good, especially if you don’t have the cash for an ultralight gortex jacket, but the weight of gortex jackets has come down significantly. I really love my event jacket by integral designs but found that it started leaking after about 1000 miles. In the end I will go with the lightest montebell gortex jacket they sell for my long distant backpacking… about 11 oz. For pants, the 7 oz montebell gortex pants. It’s expensive to be sure, but in the Rockies the extra durability and wind performance really beats the socks off anything else we’ve tried, and we’ve tried a lot of variations.
