Why This Bag Stands Out
  • The first thing you notice is the sleek, hard-shell exterior. It doesn’t just look “space-age”—it provides a physical barrier against bumps and minor impacts, protecting your iPad or tablet.
  • Combined with the integrated TSA-friendly combination lock, it offers peace of mind that most standard backpacks simply can’t match.

Frequently Asked Questions (FAQ)

A: This bag is designed for portability. It fits tablets and iPads up to 9.7 inches, but it is not large enough for a standard 13 or 15-inch laptop.

Q: Is the USB cable included?
