The Thoriums are made for mountain cold. The parka takes their performance farther. Extended for added coverage, it delivers warmth on winter’s coldest days. The lofty 750 fill-power goose down is light, efficient, and responsibly sourced. Down Composite Mapping™ strategically places Coreloft™ synthetic insulation in areas prone to moisture, a bio-derived liner reduces petroleum use, and the light, durable Arato™ 30 nylon shell has a DWR treatment to repel water. An insulated StormHood™ extends protection to give you full-coverage warmth.
