Is there one backpack I can use for work, travel and casual? Which backpack change size depending on your need? What’s the largest backpack you can take on a flight? Is there a large travel backpack with a laptop holder? Is there a smart, high quality cabin luggage bag for carry-on luggage? Are there hybrid backpacks that change capacity from small to large? What's the best softpack cabin luggage?

You can still look smart even travelling with a max carry-on backpack. And backpacks have been reinvented by Riut to be 100% secure when they are on your back. You can also use one backpack for your every day commute and for global travel with this clever, folding and expanding origami design. Meet RiutBag X35, just funded on Kickstarter.

How it works

RiutBag X35 changes size to suit the capacity you need in seconds. Use the unique folding mechanism to change from an everyday carry laptop backpack to a max carry-on, cabin bag with over 35 litres space. It's secure too, because we made safer backpacks for greater journeys. Enjoy carrying anything anywhere.

The X35 is built with a luxurious, durable and waterproof materials and a tough base. It is a smart and durable backpack for daily and international travel. The main 15 - 35 litre compartment opens suitcase style to reveal a bright, cavernous compartment. It has a mesh divider to aid with privacy and packing.

The design changes size to suit the needs of the traveller and stays secure whenever it is worn. Because no one else can get into the RiutBag X35, it lets you travel with confidence, openness and less stress.

Washing instructions

RiutBag is simple to clean: For light stains, use a damp cloth. For a complete refresh, RiutBag is machine washable up to 40 degrees centigrade. Do not use detergent: this breaks down waterproofing capabilities in RiutBag materials.  Dry naturally, not in a machine or tumble dryer.

How RiutBag is made

Each RiutBag is designed by Sarah Giblin and is handmade at a sewing machine in Fujian, southern China. This is the best factory in the world that designer, Sarah Giblin, could find. Sarah spends 3-4 months per year at the RiutBag factory working alongside the staff, improving manufacturing techniques and designs every time and catching any errors which occur naturally when new, complex backpack designs are handmade by real people. Together with Sarah, two production teams of 22 people have made every RiutBag in existence. When the RiutBags are complete, RiutBag designer, checks every single one - seam by seam, zip by zip - to ensure they are right for you.
