Thank you for viewing. This item is unused and has not been opened. I am selling it because I haven't had the opportunity to use it. Please refrain from purchasing if you are sensitive to minor imperfections, as this item has been stored by a private individual. This is a renewed model of the "IBUKI series" in collaboration with NANGA, adding a "shoulder warmer" to the IBUKI800. The shoulder warmer is a tube with padding on the shoulders that prevents the warm air inside from escaping. Approximately 900g of padding is used. The padding material uses Dacron(R) Fiberfill, a long-established polyester fiber, and is slightly more expensive than the padding used in NANGA's in-line model "Dotted Padding Bag." The soft 20-denier nylon fabric combined with it creates a gentle, fluffy feel. Please experience it for yourself. ■Color: Black/Khaki ■Size when in use: 80cm x 210cm ■Storage size: Φ22cm x 41cm ■Weight: Approximately 1,450g ■Comfort temperature: 0℃ ■Material: Fabric: 100% nylon Padding: 100% polyester ■Features: Inner surface: Single quilt structure Draft tube: A tube inside prevents cold air from entering through the zipper gaps, improving heat retention.
