The SirJoseph mummy sleeping bag Light Series Koteka III 290 190L - Blue is an ultra-light three-season down sleeping bag specially designed for participants in expeditions, extreme crossings, and mountain climbs in alpine, Arctic, or desert environments. It is also highly appreciated by enthusiasts of extremely low weight and minimal pack volume.
Thanks to the use of the new ultra-light Pertex Quantum Y outer material, the highest quality down, and functional accessories, the Koteka sleeping bag achieves twice the reduction in volume and weight compared to a classic sleeping bag with the same thermal comfort. With this sleeping bag, you will truly appreciate the minimal bulk and low weight. Every gram you do not have to carry makes a difference on a trip. The new Pertex material also provides excellent resistance to wear and prevents down from escaping.
