MOUNTAIN PASS Mummy Type Down Sleeping Bag 850FP Light Green Down Fill: 1200g (Right Zip) Weight: 1.7kg 20D Ultralight High-Density Nylon 400T Waterproof Waterproof and breathable, prevents down from escaping. Manufacturer's description: Comfortable Temperature: See photo 7 for the storage bag's description. This sleeping bag is unused, but I used a sleeping bag from the same brand with 800g of down in a tent in -5°C weather with snow, and I slept warmly. Includes a sleeping bag cover. Purchased on Amazon on October 5, 2023. Currently, I mainly use a sleeping bag with 800g of down, and I have no plans to use this one, so I am selling it. After purchase, I took it out of the bag once to check the down's loft and condition, and then stored it at home. It takes about five minutes out of the bag for the down to fully expand as shown in the photos, and I think it will be extremely warm. The down is also unlikely to clump. Also, because down is also in the draft collar, the zipper may catch a little until you get used to it.
