Wore these for the first time yesterday on a very windy and horribly rainy evening while walking the dog and they did the job beautifully. Didn't overheat in them, they didn't rustle like other waterproof trousers do and they kept the wind and rain out just as promised. The rain just beaded on the surface and rolled right off, which I almost didn't believe it would given the fabric is so soft. I'm a size 12 normally but went for the 14 for a slightly more relaxed fit (in case I wanted to wear thermals underneath) and for my 5 foot 9 height the regular length is a little shorter than I'd normally like to wear (going for the size 14 meant they sat a little lower than the size 12 did) but as I wear them tucked into muckboots when the weather is really disgusting this isn't too much of a problem.
Haven't washed them yet, but the care instructions make them sound like they should be easy to keep clean and keep their waterproofing.
So far, very impressed!
