Expedition-grade insulation for extreme environments

The Mountain Equipment K7 Women's Down Jacket is engineered for serious alpine and expedition use, combining a DRILITE® LOFT 30D outer fabric with 272g (Size 12) of 90/10 goose down at 800 fill power. Built for mountaineers operating in remote and exposed environments, it delivers exceptional warmth, weather resistance and thermal efficiency through advanced box-wall construction and expedition-focused design. Designed for alpine climbing and mountaineering, the K7 has been proven in high-altitude and polar conditions where dependable insulation is essential.

Performance & Engineering

• 800 Fill Power Goose Down Insulation – Engineered with 272g (Size 12) of 90/10 goose down and a minimum 800 fill power to provide outstanding warmth while maintaining a relatively low packed volume for expedition equipment.
• Box-Wall Baffle Construction – Built with box-wall baffles that minimise cold spots and maximise loft, delivering the highest level of insulation for prolonged exposure to harsh mountain conditions.
• DRILITE® LOFT 30D Protection – Designed with DRILITE® LOFT 30D outer fabric that is completely windproof and highly weather-resistant, helping retain warmth during storms, strong winds and snowy conditions.
• EXL Thermal Efficiency System – Engineered with the EXL system across the back of the jacket, using elasticated stitching to reduce dead air space and improve thermal efficiency when operating in extreme environments.
• Expedition-Focused Hood & Storage – Built with a Super Alpine HC Hood, Halo Collar, large internal storage pockets and multiple external pockets to provide protection and practical storage for gloves, bottles and essential equipment.

Care & Longevity

Hand wash or machine wash at 30°C using liquid detergent or a specialist cleaner, then tumble dry on a low heat with a slow spin speed to maintain loft and insulation performance. Store in a cool, dry place away from direct sunlight. Avoid high drying temperatures, fabric softeners and long-term compressed storage to help preserve down loft and weather-resistant performance.
