The original cover bag is missing, but the sleeping bag will be placed in a large Ziploc-like bag, and then a duffel bag will be provided as an outer bag. The duffel bag has a color that looks like sand has seeped into it, but it doesn't feel sandy when rubbed with a finger, and I think it's completely dyed? So I don't think the color will transfer. Also, there is a small hole in the bottom of the bag. US Military Sleeping Bag - Color: Olive Green - Size: Approximately 193cm in length - For cold regions? Filled with padding. - Features: Snap buttons, double zipper The face area can be tightened (photo 6) I don't think there are any unpleasant odors. It has a double zipper that can be opened and closed from the front and back, so you can close it from inside the sleeping bag. The snap buttons are also tough. It's made to US military specifications, and is over 190cm, so most Japanese people will fit in it comfortably.
