These got me through my winter trip to Alaska and were comfortable to about -19 degrees with an wool base layer! They are water resistant and so comfortable! I just have 2 pair and don’t need to keep both. The fit is roomy enough to layer under them, but not too big to be worn alone. I wore these without base layers to about 0 degrees and layered them for anything subzero and I was comfortable. I looked high and low for the jogger style with insulation and it was super hard to find but I am a Eddie Bauer fan for life after these!!
