The panels dividing the end compartments from the main compartment of the bag unzip — another versatile feature allowing you to customize the Aeronaut 30 to your needs.
It's confusing but the compartments actually unzip and open so you can have a larger compartment if you want that. They don't zip inside to make it a smaller bag.
