If you still think this is cold, unfortunately, please give up on winter mountain camping. (lol) Although it's an old model, it has the same specifications as the currently released AIR Plus 810. I bought it because I really hate being cold, but it was definitely overkill. I've only used it once in Yatsugatake. I thought I would use it eventually, but I've graduated from winter mountain climbing, so I'm selling it. I've taken great care in storing it, so the condition is good. Of course, there are no odors, and I've inspected each part, but as far as I can see, there are no frays or stains. I highly recommend it to those who are particularly sensitive to the cold. By the way, the photos were taken without stuffing, so please rest assured. Minimum operating temperature: -25℃ Insulation: 820FP goose down (810g) Size Total length: Approximately 205 cm Width: Around the shoulders (widest part) the red part is 65 cm + gusset is about 20 cm. *I remember there was a women's size at the time, but this is a men's size. It's a size that even someone 180 cm tall can comfortably fit in. ISUKA Isuka Winter sleeping bag NANGA NANGA ◾️Please read the profile before purchasing. ◾️No price reduction.
