cote&ciel isar Cote&Ciel Isar Rucksack Backpack Black Large Tough *Slight paint peeling on the metal fittings of the zipper pulls. This is a large-capacity bag. It has a main compartment, a laptop compartment, and a secret pocket, providing ample storage space. The most distinctive feature is its unique form that utilizes architectural curves. It's shaped like a turtle's shell, and even if it gets wet in the rain, the water will run off due to the curvature. Also, there are experimental results showing that the curved form is less susceptible to impact than a flat surface, making it a strong structure against impacts. The main compartment allows you to take things out while wearing the bag by unfastening the strap from one shoulder and bringing the bag to the front. The laptop compartment is located against your back, so you can carry it with peace of mind. The secret pocket is designed to be almost invisible from the surface, making it convenient for storing valuables such as keys and commuter passes. Also, because it fits very well against the back, you don't feel the weight as much, and it's designed to be less tiring even when worn for long periods.
