◎ Thank you for viewing. ◎ Rare item from René Maison. Sleeping bag (shlaff) - half-body (short) type Feather (feather/down) made in France. ☆ Size/Weight (please understand there may be errors) (Approx.) Length: 120cm, Opening: 62cm Bottom: 32 x 32cm, Weight: 780g When stored: Length: 33cm, Diameter: 15cm ☆ Material: Nylon. ☆ Color: Outer - Blue系. Inner - Red系. ☆ All seasons. (Cold, high altitude) ☆ Manufacturing year: 1960s to 1970s Vintage item. ☆ Used in the 1970s-1980s for continuous climbing and winter climbing bivouacs, etc., in combination with down clothing and sleeping bag covers. It was useful in the winter mountains such as Tsurugi, Hotaka, Yatsugatake, and Rishiri Island. ☆ It was much easier to move around when preparing for climbing or eating inside a Zelt. (Demezon was a dream item, and it was quite expensive at the time). ☆ Still usable in active service. ☆ It was stored by hanging it, not in a bag, so the down has not decreased much, and I think it is fluffy and can maintain its heat retention. ☆ Although the frequency of use is not high, there are *stains on the outside due to use in confined spaces such as snow caves and Zelts. (Outer blue/inner red is clean) * One spot on the outside opening, about 10cm, has been repaired with thread. (See photos 10 and 11) * The manufacturer's tag of Demezon has the name section blacked out with a marker. (See photo 9) * Please refer to the photos for other conditions. ☆ This is a very rare item. We ask that it be used with care. * Please consider this item as a used vintage item. * (Due to the nature of the sleeping bag, please refrain from purchasing if you are overly concerned about details.) ☆ A new bag will be included. (Not an original product) ☆ Shipping included (the item will be folded and shipped in a box). ☆ Anonymous shipping. ☆ Immediate purchase is possible. ☆ Please consider carefully.
