I'm selling this down jacket, which I bought for winter mountaineering, because I no longer have the opportunity to use it. * The outer layer is PrimaLoft, a blend of down and polyester that is resistant to getting wet, and the inner layer is KODENSHI ProDown, which prevents heat loss while improving heat retention, preventing cold air from entering and getting wet. * Includes a stuff sack for storage (34cm long x 18cm wide x 18cm deep). - Brand: THE NORTH FACE - Series: SUMMIT SERIES - Size: M - Color: Fiery Red - Material: KODENSHI ProDown (72% down, 20% polyethylene, 8% other feathers)
