With 1400g of the highest quality 850FP ethically sourced European Goose Down, the Expedition 1400 is designed to offer warmth and protection in temperatures as low as -40°C. Specifically designed for expedition use, the Expedition 1400 is slightly oversized to accommodate larger Expedition clothing, and uses a combination of high quality Pertex® inner and outer fabrics. Key technical features include water-resistant linings at the head and foot to prevent water ingress, longitudinal baffles to minimise down migration, and a face baffle for improved use with a hood. The Expedition range of sleeping bags are hand-filled in Derbyshire, UK.
