It was tested on various mountains in the snow half a day up to the knee. The pants did not feel anything. With extremely cold air at the peaks, I didn't feel cold at all on my legs. If you go to - temperatures, with a thermal layer inside, don't be afraid of anything. It has also eaten a lot of snow water for a long time and still nothing passed through. I should note that it already has fleece inside and is a relatively thick pants, maybe reminiscent of ski pants but not so heavy and bulky. It is excellent for hiking in the snow.
