Product Description Purchased in December 2024 at the NANGA Toma store in Toma, Kamikawa District, Hokkaido. Down jacket using "HINOC," a material blended with flame-retardant aramid. "HINOC," a unique material that blends flame-retardant aramid with cotton-like polyester fabric, is resistant to fire, a weakness of synthetic fibers. This jacket is perfect for situations where you are concerned about sparks, while still enjoying the high heat retention of NANGA down. Only European white duck down, washed domestically, is used for the down, and NANGA's unique UDD, which has been given a super-water-repellent treatment, is also used. This minimizes the reduction in heat retention caused by the down getting wet and shrinking due to water from the outside, such as during rain, or sweat and moisture from the inside during field work. The down is 90% down and 10% feathers, with a fill power of 760FP, making it a high-quality down with excellent cost performance. Worn only once, with no scratches or stains.
