Expandable Capacity for Unexpected Needs
The Tracks Expansion Backpack is designed with a base capacity of 21 liters, which can be expanded to approximately 27 liters (a 30% increase) by operating a built-in 360-degree zipper. This feature allows users to instantly accommodate unexpected purchases or increased luggage during travel, providing smart storage without the need for additional bags. It is suitable for daily use, as well as for business trips and travel where a larger carrying capacity is often required.

Uncompromised Comfort and Stability
Even when expanded, the backpack maintains Incase’s signature carrying comfort. The thick shoulder harnesses effectively distribute weight, reducing strain on the body. Additionally, V-shaped compression belts on the side panels suppress internal load shifting, ensuring a stable fit and sustained comfort even when the capacity is increased.

Smart Interior Organization
The main compartment features a simple, single-chamber design for intuitive access to belongings. It includes a brushed-lining tech pocket capable of storing up to a 16-inch MacBook and an iPad, complete with a dedicated access zipper for smooth retrieval. Furthermore, the backpack is equipped with a multi-function pocket that includes a key strap, pen pockets, and mesh pockets, as well as a band to secure a folded umbrella or water bottle upright. This single-room structure is designed for efficient organization.

Functional Exterior Features
The exterior of the Tracks Expansion Backpack features the series’ iconic vertical pocket on the front panel. Both sides are equipped with expandable pockets, suitable for storing items like water bottles. The top panel pocket, lined with brushed material, is ideal for delicate items such as an iPhone, AirPods, or sunglasses. A strap on the back panel allows for attachment to a trolley handle, enhancing convenience during travel.



This backpack combines aesthetic design with expandability, catering to the evolving demands of modern tech lifestyles.
