Erratic Plus II 1000 Lady is part of the Alpine series by the Czech sleeping bag specialist Sir Joseph. Years of experience meet the highest quality standards. They combine to create this warm down sleeping bag for winter temperatures and alpine pursuits. Its focus is clearly on minimal bulk and maximum thermal efficiency with a comfort zone down to -7°C.
The goose down comes from Europe and is arranged in the sleeping bag in so-called H-chambers. These are separated by vertical spacers which prevent the fill from slipping and cold spots forming. This sleeping bag offers a 90 to 10 down-to-feather ratio and a fill power of 650 cuin. The outer material Exel Dry Light 100 was specially developed for down sleeping bags and jackets and protects the insulating layer from moisture, condensation and extreme frost. Body moisture is also able to evaporate out.
Several practical details, like the cover flap behind the zip, the small inside pocket and the draft collar really round it off. All in all, Erratic Plus II 1000 Lady is a fantastic mountain touring and bivouak compatible down sleeping bag! ;"
