Rear Harness System: The back view reveals a dual-functional design where both bags are equipped with fully padded, contoured shoulder straps. This allows them to be carried comfortably as traditional backpacks when navigating uneven terrain or stairs.
Trolley Integration: Each backpack features a heavy-duty, single-tube retractable aluminum handle integrated into the spine. The base is outfitted with a sturdy wheel assembly and protective housing to support smooth rolling and prevent fabric wear.
