Protects you from cold

Cold gear is awesome. Keeps me warm in the coldest conditions. The compression goes well as a base for heavier layers, especially when hunting.

Been using these Under Armour cold leggings for my runs lately. These are super comfy, warm enough for the cold mornings, and not too hot once you get moving. Solid fit and great feel

I played ultimate frisbee wearing these on turf, and they helped keep my legs warm throughout the evening. Did they improve my performance? Not really, but I felt comfortable and warm, so that was nice. I'm 6'2" 210 lbs
