Lightweight, insulating, breathable Baselayer. Ideal for winter sports Snug fit thermal pants for fitted outerwear. Great for winter runs, cross country skiing, downhill skiing, etc. Breathable panels on inner leg. You can see in the last photo that you can see through them a bit. 80% polyamide and 20% wool. I bought them for a backpacking trip but decided not to wear them ultimately, so they are new without tags. Very soft and stretchy. Inseam 27”
