Expandability:
Unzip the middle zipper to lengthen the bag by 5 inches allowing you to carry enough for an overnight trip.
Load Examples
The bag's general dimensions were designed around the grey camera case creating a snug fit to prevent items from tumbling and keeps items stacked in vertical order.
Middle Zipper = Midizip
The middle zipper is the highlight of the bag and is where the name is derived from.
Inside
Trapezoid Opening
The trapezoidal top opening completes the bag's milk carton appearance.
Side Access Flap
A discreet side flap can allow access to small items like gloves or a wallet.
Reinforced Base
An 1 inch thick upholstery foam base helps the bag always stand upright and keeps contents inside safe during drops or tumbles.
Real World Use
I packed it up and took it on my flight home for winter break. Valuables inside such as my camera and iPad felt confidently protected. The backpack felt comfortable to carry in both normal and expanded configuration.
