Product Information

The HEROIC KNIGHT HK8228Y is a slim, lightweight backpack built for daily commutes, office work, and university. If you only carry your laptop, charger, and a few essentials, this bag keeps a thin, neat profile. It stops you from having to carry a bulky, half-empty bag on normal workdays, meaning you can move through crowded trains and buses without bumping into people.

The main feature of this bag is its thin design. It is only 9cm deep, keeping it tight to your back. It comes in two sizes to fit either a 15.6-inch or 17-inch laptop. It also features an external USB port, so you can drop a power bank inside and charge your phone while walking, and a small card pocket on the shoulder strap for quick access to your bus pass or train ticket.

  • Two Size Options: Available in a 15.6-inch version (0.7kg) or a larger 17-inch version (0.8kg) to match your laptop size.
  • Built-in USB Port: Plug your power bank inside the bag to charge your phone on the move.
  • Shoulder Strap Card Pocket: A handy slot on the strap holds your transit pass or debit card for fast access.
  • Dedicated Tablet Slot: Features a separate inside sleeve designed to protect an iPad up to 12.9 inches.
  • Water-Resistant Fabric: Made from high-density Oxford cloth that keeps rain from soaking through to your electronics.
  • Breathable Back Padding: Lined with air-mesh cushioning to keep your back cool and comfortable during long walks.

The HEROIC KNIGHT HK8228Y handles rain and daily wear easily. The waterproof outer fabric keeps your paperwork and devices dry during sudden showers, and the whole bag wipes clean with a damp cloth. It is structured with an external frame so it keeps its shape over time, and it features a solid, rigid top handle if you prefer to carry it like a briefcase.

Inside, the bag uses a smooth polyester lining to prevent your laptop from getting scratched. Multiple small pockets keep your pens, mouse, and phone cords organised instead of tangled at the bottom. With its clean, solid black look, it fits perfectly into professional meetings, office spaces, or college classrooms.
