Nanga Inner Sheet An inner sheet made of breathable polyester mesh. By placing it inside a sleeping bag, it reduces stickiness against the skin, providing a comfortable night's sleep. It also helps keep the inside of the sleeping bag clean. It can be used inside a sleeping bag, and because of its excellent breathability, it can also be used alone in summer for low-mountain hikes and camping. The half-zipper design and lightweight construction make it easy to carry. It also comes with a storage bag, allowing for compact storage and preventing it from taking up too much space in your bag. 《Product Specifications》 ● Fabric: Polyester mesh ● Size: Regular (80cm x 210cm) ● Storage Size: 12cm x 18cm ● Total Weight: Approximately 425g ● Color: Beige I purchased this in the Himalayas last year, but I haven't had a chance to use it, so I'm selling it.
