The Astrum LB310 - One Bag for Every Day. Every Trip.
A premium PU travel backpack for professionals and frequent travellers. The LB310 starts at 20L for daily carry and expands to 28L when your needs grow - one bag from Monday commute to weekend trip.
Expandable 20-28L - Adapts With You
The expansion zip adds 8L in seconds, taking the bag from 46 x 32 x 18cm to 46 x 32 x 22cm. It remains within most airline carry-on size limits when expanded.
Up to 17" Laptop + External USB Charging Port
A dedicated padded laptop compartment fits laptops up to 17 inches. The external USB-A port connects to a built-in internal charging cable, allowing you to charge your phone from a power bank stored inside the bag without opening it.
PU Water-Resistant Exterior
The premium PU coating helps repel light rain and splashes. The professional finish makes it suitable for business, office, and travel use.
Airflow Foam Back Padding - All-Day Comfort
Multi-panel airflow foam back padding helps reduce heat and pressure during long commutes. Adjustable padded shoulder straps and a reinforced dual carry handle provide comfortable carry options. The LB310 weighs only 0.8kg empty.
Multiple Compartments
A dedicated laptop compartment, main storage area, front organiser pocket, and internal/side pockets provide space for your passport, phone, wallet, power bank, and accessories.
