Arc'teryx Men's Thorium Hoody

The Thorium Hoody is engineered for frigid environments, delivering exceptional warmth through high-loft 750 fill-power grey goose down. This RDS-certified insulation provides outstanding thermal efficiency, ensuring a high heat-to-weight ratio for reliable performance during intense cold. Utilizing Down Composite Mapping™, Arc’teryx strategically places Coreloft™ synthetic insulation in moisture-prone zones to maintain warmth even when damp. The exterior features a lightweight yet durable Arato™ 30 nylon shell, treated with a DWR finish to effectively repel light rain and snow. The jacket's interior uses a bio-derived liner to reduce environmental impact, while the adjustable, insulated StormHood™ provides additional protection. This combination of sustainable materials and technical design creates a versatile, robust layer that excels as either a standalone piece or a heavy mid-layer.
