Dulles backpacks are characterized by wrinkles created by the material and a square silhouette. The main body material is Limonta's nylon "Fenzy". The main storage is compatible with A4 size and has a pocket that can store a 13-inch PC, as well as multiple pockets inside and outside the bag that can efficiently store small items and documents necessary for work. The backpack belt is equipped with a belt ``ZeRoG Fit'' that has a load dispersion effect. It makes traveling with a backpack more comfortable and relieves stress from your body.
