I bought the Trenton Pants few days ago and since then worn in the rain and snow storms around 0 degrees (no function underwear). Conclusion: It keeps very dry, normal rain does not come through (very violent had I not yet). It is also fairly windproof This, together with the roughened inside leg for sufficient heat. Nevertheless, it is so breathable that one does not get warm.
I fit perfectly, and I'm rather tall and slim and therefore benefit from the more narrow Vaude-sections. From the looks of it is great, I have actually been asked in black and am from a friend, why I'm running around in a kind of suit pants ...
All in all, a powerful all-around outdoor pants highly recommended, especially at the price.
