Performance & Engineering

• Premium 800 Fill Power Goose Down: Engineered with 200g of 90/10 800 fill power goose down to deliver an outstanding warmth-to-weight ratio for mountaineering, ski touring and remote trekking where dependable insulation is critical.

• Dual-Layer Offset Baffle Construction: Designed with a dual-layer offset baffle construction that eliminates cold spots caused by stitched-through seams, helping maintain consistent warmth in windy and exposed conditions.

• DRILITE® LOFT Weather Protection: Built with DRILITE® LOFT 20D fabric and a durable water-repellent finish to provide complete windproof protection and reliable resistance to snow, light precipitation and spindrift.

• Heat-Reflective Internal Technology: Utilises a reflective internal scrim that helps retain body heat by reflecting warmth back towards the wearer, increasing thermal efficiency without significant weight gain.

• Mountain-Specific Design: Combines an Insulated Mountain HC Hood, insulated collar, elasticated cuffs and dual-tether hem drawcords to maximise protection in exposed terrain while remaining compatible with a climbing helmet.

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 to maintain loft and insulation performance, and store in a cool, dry place away from direct sunlight. Avoid high drying temperatures and always follow the manufacturer's care guidance to preserve down loft and the durable water-repellent finish.
