The Mark Ryden King Vacuum is a game-changer in the travel industry, designed for those who want to pack maximum gear into a cabin-sized backpack. It features a unique dual expansion system: integrated vacuum compression and a 10cm expansion zipper.
This is a pioneering product with a built-in vacuum pump integrated directly into the valve. No extra gadgets or external pumps are needed. Simply activate the system to shrink your clothing bulk by up to 50%. When you need even more space, unzip the expansion gusset to transform the pack from a sleek 20L daily carry to a massive 35L travel suitcase.
