Pantaloni Primal Donna

Wore these for a windy 8-mile trail run at about 25°F and my legs never felt the bite. The fit is tight but moves with you, no bunching behind the knees on the climbs.

I’ve worn these on three freezing morning trail runs and my legs stayed warm the whole time without that bulky feeling you get from other thermal layers. The tight fit actually moves with my stride instead of riding up, which is rare for winter tights. Finally found bottoms that work for cold-weathe

These kept me properly warm on a frosty trail run without any bunching under my pack. The tight fit through the hips and thighs is perfect for staying aerodynamic when the pace picks up on descents. I've already ordered a second pair for those brutally cold morning hill repeats.
