Backpack XDDESIGN FLEX GYM BAG — 24 L, fits 15.6 inch / 39.6 cm tablet/notebook, padded adjustable straps, black

The XD-Design FLEX GYM BAG is a versatile casual backpack that combines business functionality with gym-ready capacity. Made from recycled plastic in a sleek black finish, it measures 300 × 200 × 460 mm and converts quickly from a compact 16 L business backpack to a 24 L gym bag by expanding the front pocket. The design includes anti-theft features and dedicated pockets to keep devices and personal items organised and secure.

Advantages

This backpack offers convertible capacity for work and sports, anti-theft protection with no front access and hidden zippers for the main compartment, and an RFID-protected pocket on the back for wallets, phones and cards. A built-in USB charging port is integrated into the shoulder strap for on-the-go device charging, and a sunglasses holder on the strap adds convenience. The bag is constructed from recycled plastic, supporting a more sustainable choice.

Recommendations

To maintain the backpack’s appearance and recycled fabric, clean spots with a damp cloth and avoid heavy machine washing. Use a compact power bank placed in an internal pocket when using the USB charging port, and keep valuables in the RFID pocket when in crowded areas.
