In addition to these compartments, there is a heat-insulated pocket for a bottle at one end of the bag and a large heat-insulated compartment at the other end to keep your lunch cool even in summer. The bag can be easily and conveniently carried on the shoulder taking advantage of the strong and padded carrying strap.
