PAC-01 Coyote A 12L backpack, the smallest size for easy mountain trips. The pocket can store a 500ml plastic bottle. To prevent contents from falling out when you look down, it can be adjusted with bungee cords. The shoulder straps use thin, wide padding to distribute the load on your shoulders. Tightening the shoulder straps and securing the end of the tape further increases stability. It fits snugly on your shoulders, allowing for complete freedom of movement around your waist. The top is a roll-top type that allows you to adjust the internal capacity. The diagonally running zipper on the other opening makes it easy to access items stored at the bottom. All materials are X-Pac, which can withstand light rain. Size: H470mm x W270mm x D60mm Capacity: 12L Weight: 260g Shoulder Size: FREE Material: X-Pac VX21 Never used for hiking.
