The Alberton roll backpack uses Alberton's Army Duck, which was developed according to the U.S. military's military material standards. The canvas woven at a high density, which is not in Japan's standards, has excellent durability. We dyed it in an original color that is particular about quality at a dyeing processing factory in Japan. The belt part is made of Nume leather and is firmly held by a die-cast buckle. There is a through zipper on the side, so it is easy to put in and take out. Pockets are placed on the surface, sides, and inside for convenient use size Vertical 62 cm (44 cm with mouth bent) Horizontal 30cm Gusset 15cm Color: 3 colors Koyote Khakaidra Kuro
