This is the ARC'TERYX LEAF α LT, a special military line manufactured for military and law enforcement agencies and not intended for general distribution. It's a fully waterproof and breathable, lightweight "3-layer shell jacket" designed to perform in harsh environmental conditions. Suitable for all-weather wear from spring to autumn, it's also ideal for layering in cold environments by adding fleece or down as inner layers. The shell, with its excellent wind resistance and extremely high breathability, prevents rain and wind from entering while allowing sweat to escape. This wind resistance and breathability help to prevent body temperature from dropping while reducing the risk of overheating during activity. As shown in the 11th photo, there is a small stain, but there are no major scratches or stains that would hinder wear. The water repellency has diminished somewhat, but it should be restored by using a water-repellent detergent and a dryer.
