The SirJoseph Erratic Plus III 850 mummy sleeping bag - 200 cm - left zip - is a sleeping bag from the Alpine series, suitable for trekking below Everest or climbing Island Peak or Mera Peak. The sleeping bag offers protection against wind and water as well as perfect thermal insulation.
These down sleeping bags provide excellent support during expeditions in mountainous regions. The sleeping bags are designed with a focus on minimal pack volume, maximum thermal comfort, and protection against rain, snow, frost, and wind. The Erratic Plus III 850 sleeping bag is designed for extreme alpine conditions and offers reliable protection against harsh weather. It even allows you to sleep under the open sky. The Alfa chamber construction and specially developed close-fitting hood shape provide even better insulation.
The outer shell of the sleeping bag is made from Excel Dry Light 100 (nylon with PU lamination). The efficient membrane keeps moisture from the outside out while allowing moisture produced by the body to escape. The ripstop structure is abrasion-resistant and improves tear protection.
