If you have an UDD BAG (Ultra Dry Down Bag), you won't need a synthetic fiber sleeping bag. The UDD BAG, which uses high-quality down, minimizes the reduction in heat retention caused by the down getting wet and shrinking due to rain, humid places, or sweat while sleeping. The UDD BAG is perfect for customers who: Want a lighter and more compact sleeping bag than conventional ones Want to save time when storing Want to reduce stuffiness Because the fabric is not coated on the back, it is lightweight, and air can be exchanged more smoothly than with conventional fabrics. There is less stuffiness, and the down expands smoothly. The 15dn thin and soft fabric allows for compact storage. Nanga down sleeping bags come with a lifetime warranty, which is automatically applied at the time of purchase. There is no registration certificate (postcard) or the like. Please check the manufacturer's website for any questions. This is a 3-season model that is lightweight due to its rational structure and can be used widely from high mountains in spring and autumn to low-altitude mountain climbing in winter. - From the manufacturer's catalog, Comfortable temperature (COMFORT) 1°C / Lower limit temperature (LIMIT) -4°C / Extreme temperature (EXTREME) -21°C Fabric: 15dn nylon shiré water repellent Internal structure: Trapezoidal box quilt structure Maximum shoulder width: Approximately 80cm Suitable height: Up to approximately 178cm Down fill: 450g Fill power: 770FP Storage size: Approximately φ14 x 30cm Total weight: Approximately 825g Country of manufacture: Japan *Please note that we may not be able to contact you on Saturdays, Sundays, holidays, and long holidays (GW, Obon holidays, year-end and New Year holidays, etc.).
