40L Expandable Capacity

This Lumesner travel backpack expands to 40 litres, providing room for clothing and gear across three to seven days of travel. The unisex design suits men and women who need a single carry-on that works for both weekend trips and longer stays.

Flight-Approved Carry-On Fit

At standard carry-on dimensions the bag fits overhead bins and under seats without gate-check hassles. A rear luggage strap slides over rolling-suitcase handles for hands-free transit through terminals. Four included packing cubes separate outfits, toiletries and shoes to keep contents organised.

35 x 10 x 30 Inch Frame

The polyester shell measures 35 by 10 by 30 inches when fully expanded, giving a clear sense of the space available. Ventilated back padding and adjustable shoulder and chest straps distribute weight for extended wear. An external USB port allows on-the-go phone charging via a power bank stored inside. Travellers needing more than 40 litres or a dedicated laptop sleeve larger than the main compartment will find the capacity limiting.
