50L expandable capacity

This backpack expands by two inches to reach a 50L volume, suitable for three to seven days of travel gear. When unexpanded it meets most IATA carry-on limits and fits in overhead compartments or under the seat. It includes packing cubes, a drawstring shoe bag and a dedicated compartment that holds a 17.3-inch laptop and a 12.9-inch iPad. The black water-repellent polyester construction is built for repeated use.

Honeycomb back pad and adjustable straps

A multi-surface airflow design uses a honeycomb back pad and adjustable shoulder straps to improve breathability during extended wear. The water-repellent polyester fabric protects contents from light rain without adding bulk. An anti-theft zipper pocket on the rear panel and a luminous strip on the straps add security in low-light conditions. The pack weighs 3.3 lbs empty.

Stowable straps convert to duffel style

Shoulder straps tuck into a zippered back panel to transform the backpack into a duffel-style carry option. A luggage strap on the rear slides over a suitcase handle tube for hands-free transport through terminals. Fifteen interior and side pockets plus a cup pocket keep items organised and accessible. The 21.3 by 7.87 by 13.8 inch frame balances capacity with airline compliance.

Questions about this item

How do I expand the backpack from its standard carry-on size to the full 50L capacity?

Unzip the expansion panel to add 2 inches of depth, increasing the volume to 50L for 3-7 days of gear; when collapsed it measures 21.3 x 7.87 x 13.8 inches to meet most IATA overhead and under-seat limits.

What maintenance will the included packing cubes and shoe bag need over time?

The large cube, medium cube, small waterproof cube with transparent side, and drawstring shoe bag are all removable; hand-wash with mild detergent and air-dry to keep the water-repellent polyester fabric performing.

At what point does the back-panel airflow system stop keeping me cool during a long carry?

The honeycomb back pad and adjustable shoulder straps with multi-surface airflow design dissipate heat until the 3.3 lb pack is fully loaded near its 50L limit, after which sustained carry comfort decreases.
