This is a LOGOS Silky Inner Sleeping Bag. Total weight: 360g Length: 210 x Width 84cm Storage bag: 20 x 13cm Main material: Antibacterial and Odor-Resistant Silky Moist Cloth LANXESS's Silvadur antibacterial treatment technology is used, providing antibacterial and odor-resistant effects for comfortable use. When used as an inner layer inside a sleeping bag, it improves heat retention and allows for a dry and comfortable sleep. It can also be used as an outer layer, like a sleeping bag cover. Machine washable. I have used it twice, and it is in clean condition with no stains. It has also been washed and is ready to use. Please consider it.
