This is a Sea to Summit travel liner, made of 100% silk. It's thin, light, warm, and durable, so it's a good idea to have one on hand in case of emergencies. It has been folded for a long time, so there are wrinkles, but there are no problems with use. It is in a clean condition with no stains or tears, but it is a used item, so please refrain from purchasing if you are concerned about minor details. The stuff sack has some dirt. Please check the 4th photo. Length is about 200cm, width is about 85cm, Weight is about 200g, as shown in the image. To reduce shipping costs, I will take the liner out and fold it for packaging and shipping. Thank you for your understanding. - Brand: SEA TO SUMMIT
