This is a masterpiece from the US ARMY, the "FIELD PACK." This is a rare all-black model. The size is M, which is the perfect size for daily use. This design is popular among soldiers for its versatility, and it is said that many soldiers still use it today. It features a large-capacity main space with loop closures and three large pockets with snap button closures on the front, making it exceptionally storage-friendly. Both the main space and the pockets have drainage holes at the bottom, which are designed for water drainage, ventilation, and to prevent the accumulation of debris. There is webbing on both sides, making it convenient to hang other items (ARMY allows for the attachment of additional pouches). The capacity is estimated to be around 30 liters, and it can easily store supplies for a 2-3 day stay, making it very practical. The material has an elegant, thin satin-like sheen unique to black, with a smooth, comfortable feel and excellent durability like Cordura. There is a letter on the back with the model name, etc., which is subtly noticeable. The details are as follows: FIELD PACK.COMBAT.NYLON.LC-1 DYA 180•12•C•4034 C465•01•018•9102 MEDIUM YMCL KY.
