The Diadem Warm Long Down Sleeping Bag from Salewa looks like a true professional in terms of sleeping comfort at first glance. Thanks to the high-quality filling materials, it offers exceptional insulation performance, keeping the sleeper pleasantly warm even in low temperatures. The sleeping bag is designed to be longer, making it perfect for taller individuals. It is important that the feet and head do not touch the ends of the sleeping bag under tension, as this can hinder optimal insulation. The thermal collar can be adjusted around the upper body to prevent the escape of warm air that has already been heated by the body. The outer materials of the sleeping bag are also resistant to moisture. They are DWR treated, ensuring that water is repelled. The continuous 2-way zipper allows for comfortable entry and exit. Additionally, the sleeping bag can be combined with other Salewa models and zipped together to form a double sleeping bag.
