●Natural product: we deliberately rely on cotton and silk and do not use plastics such as polyester and microfibre in the sleeping bag and packaging. Be a part of it too - nature will thank you! ●Ultra light: at only 170 g - achieved by the optimal combination of 70% cotton and 30% silk. Durable and robust, as all heavily loaded areas have been cleverly reinforced with another panel of fabric. Small pack size - with aluminium carabiner for flexible attachment to the backpack. ●Comfortable: extremely soft skin feeling thanks to the unique material. No unpleasant "sticking" to the skin like 100% silk. Thanks to the generous dimensions of 220 x 90 cm, nothing stands in the way of a restful night with plenty of freedom of movement. ●Hygienic: protection against foreign beds and dirty bedding. Practical cushion compartment for safe storage without slipping out. Also suitable as a lining to protect your sleeping bag and to increase the heat output. ●Reliable: We are sure that we have developed a travel sleeping bag for your requirements. If you are not 100% satisfied with your sleeping bag, then send it back and get your money again. No ifs or buts!
