Thank you for viewing. This item combines a daypack and a sacoche bag. The sacoche can be detached from the daypack and used separately. The sacoche can also be attached not only to the front but also inside the main compartment to increase storage space. The daypack has ample storage space, including a padded PC storage space and a hidden pocket on the back. This is a noteworthy item that offers a variety of uses. ■ Material: Nylon ■ Size: Width 30 x Height 47 x Depth 15 (cm) 700g Thank you.
