It is lightweight but equipped with plenty of storage space, including a large front pocket with gathers and side pockets, an inner sleeve with a bud that can hold a laptop up to 15 inches, and a pocket on the top of the front. The fabric of the main body is made of textured nylon, which has a unique texture with a slightly rough feeling and fine irregularities due to the ingenuity of the weave method. It is soft to the touch, but it is designed so that the silhouette does not fall off when you carry it on your back, so it can be used in a wide range of scenes without being too casual. In addition, the back is made of a material that dries quickly. It reduces sweat on your back and allows you to carry it comfortably. -Spacious main compartment for easy storage of luggage -Expandable water bottle pockets on both sides -Inner padded sleeve for laptops up to 15 inches -Large gathered pocket on the front -Accessory pocket with zipper for convenient storage of small items -Padded back panel -Straight-cut padded shoulder straps -Cord Zip Puller Specification: -Capacity: 28L -Weight: 0.47 kg -Size: H48 x W30 x D18 cm -Strap length: Minimum approx. 40 ~ Longest approx. 75 cm (measured from the base of the shoulder pad to the base of the webbing belt) -Material: 100% 420 denier recycled nylon
