Armor Shell Travel Backpack with TSA Lock

The Armor Shell is built for the traveler moving through airports with a laptop, tech gear, and valuables — and no interest in worrying about any of it. A rigid ABS exterior protects everything inside, a built-in TSA lock secures the zipper, and the expandable body adjusts from a slim daily pack to a full travel carry-on when you need the room. Key Features Hard ABS Shell: Rigid exterior holds its shape under pressure and protects contents from drops and crowded overhead bins. The angular panel design reinforces the structure across the entire surface — it's functional, not just aesthetic. Expandable 15L → 23L: Collapses to 11cm deep for everyday use. Pull the expansion panel out to 19cm for travel days, adding 8L of packing volume without changing the footprint. Built-in TSA Combination Lock: 3-digit TSA-approved lock secures both zipper pulls on the main compartment. No padlock needed — set your own code directly on the bag. USB Charging Port: External port connects to a power bank stored inside. Charge your phone on the move without opening the backpack. Travel-Ready Build: 180° clamshell opening lays flat for easy packing; air-cushion padded back panel and straps; rear luggage strap slides over a rolling suitcase handle. Dimensions Normal: 18.1" × 11.8" × 4.3" (46 × 30 × 11 cm) Expanded: 18.1" × 11.8" × 7.5" (46 × 30 × 19 cm), 1.39 kg (3.07 lbs)
