02 WHY IT WORKS
Less switching.
More moving.
The Transit Pack is organized around transitions: from home to office, office to training, or gate to hotel.
15.6-inch laptop carry
A separate rear compartment keeps compatible laptops away from the main load.
Layered organization
Front access, internal zip storage, a key attachment and multiple sections reduce loose-item clutter.
Oxford exterior
A clean black Oxford-fabric shell gives the pack a low-profile look across work, sport and travel.

About CASSIUS08 QUESTIONS / ANSWERS
Useful before you decide.
For order-specific questions, the CASSIUS support team is available through the Contact page.
Contact usHow does the expansion work?
A perimeter zip increases the depth of the main section. Keep it closed for a slimmer daily profile and open it when the load grows.
What laptop size does it fit?
The current product specification lists compatibility with laptops up to 15.6 inches. Fit can still vary by device shape and protective case.
Is the backpack waterproof?
The exterior is listed as Oxford fabric, but the pack should not be treated as fully waterproof or submerged. Protect electronics during sustained or heavy rain.
What does the USB feature do?
It provides external connection access for a compatible personal charging setup. The backpack itself does not generate power.
Which colors are available?
The product information lists Black, Green and Blue. The options currently available can be selected on the product page.
