The Expedition 1400 Sleeping Bag from Rab has a very impressive warmth to weight ratio, it's designed for use on expeditions to 8000m peaks and in polar environments. With 1400g of the highest quality 850FP European Goose Down, it is designed to offer warmth and protection in temperatures as low as -40°C. Specifically designed for expedition use, it's 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.
