Product description
Koteka II 850 Lady the Czech sleeping bag specialist Sir Joseph is an ultralight equipment sensation! This sleeping bag easily secures the top spot for high-end down sleeping bags at an unbeatable 1,160 grams and with a comfort range down to -10°C. The perfect choice for demanding mountaineering and expeditions!

The ultralight Softex material which weighs just 28 grams per square meter and the high-quality goose really tip the scales in this bags favor. Both the inner and outer material are favored for ultralight equipment as they are highly breathable, windproof and water repellent. The European down has a fill power of 800 cuin which gives it an excellent expansion force and is fixed in so-called H-chambers. These ensure that the fill is uniformly distributed and prevents the formation of cold spots. The ratio of down and feathers is 95:5 - a true sign of excellent thermal efficiency quality.

Last but not least, Sir Joseph has completed the Koteka II 850 with a 3D draft collar, a preformed hood with drawstring and a two-way zip with insulated cover flap. A heat to weight ratio that’s really hard to beat! ;"
