A warm, highly breathable pant for mountain runs in frigid, dry conditions, the Norvan Insulated Bottom uses a hybrid design to balance airflow, thermal performance, and durability. At the top of the leg, Fortius Air 20 fabric delivers air permeability and wind resistance, and lightweight Coreloft insulates. Below, breathable Chira™ nylon knit adds ventilation. All the materials stretch to free your stride, and a long ankle zip opens wide to easily fit over your shoes.
