hi, can you told me how facing cold without insulation?
Pretty wind proof but you will want to put on a base layer for sure. Maybe more depending on how cold of temps you are in
I have these pants in the woman's model- same Gortex. I was skiing the other day in -16° weather with medium weight long underwear and I was amazed how warm I was on the bottom! The wind just doesn't penetrate them at all! Great pants, great brand, great quality!!
