This is a great backpack in nice used condition! The biggest main compartment with a padded laptop sleeve protects your laptop safely. Net pockets on both sides can store your water bottle, umbrella, or other small gadgets. The pocket on the bottom fits your shoes perfectly if you want to carry a pair of shoes with your travel. The MOLLE suspension system expands to attach more items. The two thick foamed banded parts on the back part & padded shoulder straps follow the concept of ergonomic design. They disperse the pressure on your shoulders to make you feel more comfortable when you put on it. The net foam helps dissipate heat in summer days to ensure you keep in refresh state.
