MOUNTAIN HARD WEAR 800FILL Sleeping Bag Used twice. Used by a non-smoking woman. Length: Approximately 210cm Weight: Approximately 1200g Purchased at Sakaiya Sports for around 45,000 yen. What is 800FILL? It indicates that 800g of down fills a volume of 300 cubic inches. The higher the fill power, the smaller the volume and the lighter and warmer the down product. 800 fill power down allows for the same size product to be made with less down, providing high heat retention and being lightweight, making it suitable for mountaineering and outdoor activities. A sleeping bag cover is included on the outside, allowing for even greater warmth. There is a mark where a name was written and erased, but Thank you for your understanding.
