Performance & Engineering

• High-Loft Duck Down Insulation: Engineered with 296g of 90/10 700 fill power duck down to deliver substantial warmth while maintaining a relatively low packed size for mountain travel and cold-weather layering.

• DRILITE® LOFT Weather Protection: Built with DRILITE® LOFT 40D outer fabric and a durable water-repellent (DWR) finish, providing complete windproof protection and reliable resistance against snow, spindrift and damp conditions.

• Stitched-Through Baffle Construction: Designed to keep insulation evenly distributed and minimise down migration, helping maintain warmth across key heat-loss zones including the shoulders, chest and hood.

• Protective Removable Hood: Combines a zip-off insulated Mountain Hood with a wired peak and adjustment system, allowing users to balance weather protection, weight and packability depending on the objective.

• Mountain-Focused Functionality: Features a 2-way YKK® Vislon® front zip with insulated baffle, adjustable cuffs and dual-tether hem drawcords, helping seal in warmth whilst maintaining comfort during active mountain use.

Care & Longevity

Hand wash or machine wash at 30°C using liquid detergent or a specialist down cleaner. Tumble dry on a low heat with a slow spin speed and store in a cool, dry place away from direct sunlight. Avoid high-temperature washing and drying, and always follow the manufacturer's care guidance to maintain loft, insulation performance and the DWR treatment.
