Armor Shell Flex - Expandable Hard Case Backpack 20–26L
A rigid shell backpack that expands when you need it to — and stays slim when you don't. The Armor Shell Flex carries 20L in its standard configuration and opens up to 26L with a +7cm expansion, giving you the extra space for a weekend getaway or a heavier office day without lugging a second bag.
The PC+ABS shell is scratch-resistant and splash-proof, and the 180° clamshell opening gives you instant full access to everything inside. A built-in TSA combination lock keeps your bag secured at the airport, while the USB port keeps your devices charged on the go.
