Purchased in July 2024. New, unopened item. Retail price is 68,530 yen (tax included). Thank you. The following is the manufacturer's description: The Spark Sp3 is a model designed for sub-zero temperatures. Ideal for winter missions where you want to reduce your load. The entire structure uses a box baffle construction to enclose more down and eliminate cold spots. It's an expedition-sized mummy type, providing ample space. Vertical baffles are placed from the torso up to prevent down from shifting. The half-length zipper has two sliders for excellent ventilation and ease of use. The water-repellent treated Ultra-Dry Down almost completely eliminates moisture that can negatively affect the down. It protects the down from atmospheric moisture and prevents condensation inside. The use of Ultra-Dry Down makes it suitable for harsh environments such as alpine climbing and adventure races, where every gram counts.
