The following information is from the manufacturer's website: ■Comfortable use temperature: -5°C / Lower limit temperature: -10°C ■Short (up to height 165cm), Regular (height 166cm - 178cm), Long (height 179cm - 185cm) A compact model suitable for 4 seasons (spring, summer, autumn, winter) The fabric uses water-repellent nylon. The down uses UDD DX (770FP), which is high-quality, high-performance down with super water-repellent treatment applied to DX (Spanish white duck down). The biggest weakness of down is getting wet. This is because when it gets wet, the down does not expand sufficiently, and the heat retention decreases. UDD has solved this problem. Therefore, you can use it without worrying about getting wet from condensation, etc. By using thin 15dn nylon fabric and high fill power down, it expands quickly. By shortening the expansion time, you can quickly protect yourself from the cold. Because it uses thin and light fabric, it can be carried more compactly and lightly. UDD: High-quality, high-performance down with a 770FP rating and water-repellent treatment. The down, which has been replaced three times during the rearing period in a rich natural environment, has large down balls, is durable, and is of high quality. Super water-repellent treatment has been applied to such cost-effective DX down. Box quilt construction is adopted. A mesh cloth is placed between the outer and inner fabrics to prevent the down from shifting and to warm evenly. Shoulder warmer: By attaching a down-filled tube to the shoulder area, it prevents the entry of cold air and prevents the warmed air from escaping. Draft tube: A down-filled tube is provided along the zipper to prevent cold air from entering through the zipper gaps and improve heat retention. Drawcord: A drawcord is provided around the face to warm the face area.
