I have found them very good. Keeping my legs perfectly dry through a lot of crappy weather for the last two years.
However i wore them for half an hour walking the dogs last week in the pissing rain and they leaked, badly. Dont know what the problem is. Their is a liner, so i cant see the seams to see if the tape has come off and that is where the water is coming in, or the fabric has given up, but i was wet all down one leg and between my legs (har har, no jokes)
hmm...
