If you want to go downhill, you can buy 1500G, about 1,800 yuan, but it is better to use the 2000G Tibetan mountaineering team. You can buy it from OZARK Beijing, Beijing Weitu Building. It seems to be more than 2,000 points and it is 8000 meters. Use it. Buying down sleeping bags and refilling them is a hassle. It's better to look for the skin directly. But Beijing can't find a decent hide. A few of my friends have been waiting for a long time. And the skin has the largest amount of velvet, and different volumes fill different amounts of velvet. This is one of the reasons why I don’t claim velvet. BTW: There is an important indicator to measure the quality of cashmere: Fill power. MH brother previously described "Fill power is the number of cubic inches of volume of an ounce of goose down under 68.4 grams of pressure. The higher the FP, the better the quality of goose down, but also the more expensive. High quality sleeping bags are now used 750-800 + , but generally 500-600 is also a lot." OZARK does not mark this data, most of the domestic can buy sleeping bags are also not standard.

OZARK sleeping bag use experience to read the full text >>
I have an old OZARK sleeping bag of 1000g velvet, bought last year. This year's Spring Festival, outside the tent at Xiaowutai Mountain, it's 20 degrees. There should be no problem if you climb 6000 meters. It's just that leakage is more severe. I wonder if there is any improvement in the new style.
