The overall package is relatively small for all the items it can hold. It has two major compartments. This is to help consolidate all of the items the user carries climbing on/off machines.
The larger cooled area is designed to hold lunch and beverages such as a 6-pack, sandwiches, fruit, and other small snacks. The non-cooled compartment is dedicated for laptops, tablets, magazines, clipboards, or other important work-related paperwork.
