For performers heading into extreme areas who demand reliable insulation in variable conditions – choose Salewa’s Diadem Extreme sleeping bag!

Being a naturalally occuring material is ecologically better than synthesised materials - requiring energy to produce and do not bio-degrade.

The Diadem Extreme provides an optimal sleeping experience in extreme conditions with its mountain performance tapered design, box wall construction baffles and full-length two-way YKK zip. Maximum loft and a minimized weight are ensured by the elimination of dead air space, while the large insulating draft tube and pre-formed thermo collar keep hot air from escaping during movement. The ergonomic footbox helps to keep feet warm through its special baffle system, adding even more efficiency in cold climates. An easy-run drawstring affords greater ease of use when conditions become difficult, with an internal pocket for extra convenience. It is ideal for those up to 185cm tall, coming supplied with both a water-repellent dry bag and storage bag - ideal for keeping your down uncompressed for lasting loft performance. Make sure you're ready for any outdoor challenge with this trusty and reliable sleeping bag!
