    FAQ

    How does the vacuum compression system work?

    Place compressible clothing inside the vacuum compartment and fully close the zipper and valve. For the best compression results, use the Air Pump Pro. Use the expandable zipper for even more packing space.

    How many days can I pack for with the Airback FLEX?

    You can pack for approximately 2–4 days of travel, depending on what you pack and how you use the compression system.

    What size laptop fits inside the Airback FLEX?

    The Airback FLEX fits laptops up to 15 inches.

    Will the vacuum compartment stay compressed during my trip?

    Yes. Once compressed and properly closed, the vacuum compartment stays compressed throughout your trip.

    Is the Airback FLEX water-resistant?

    Yes. It is water-resistant and designed for durable, everyday travel.

    What is the difference between the Airback FLEX and the other Airback models?

    The Airback FLEX combines the convenience of a backpack with built-in wheels, giving you the flexibility to carry or roll it while travelling. 

    Choose the Airback GO for a compact underseat backpack without wheels, the Original for a classic carry-on backpack, or the MAX for maximum packing space with backpack and roller functionality. 

    Prefer a suitcase? Choose the NEXT if you prefer a full carry-on suitcase or the MORE for a softshell check-in suitcase.

    Do I need the Air Pump Pro to use the Airback FLEX?

    No, the Air Pump isn’t required. However, we recommend it for the fastest and best compression results. The Air Pump Pro is compact, portable and rechargeable, so you can compress your Airback in seconds, wherever your trip takes you.

    Uno zaino eccezionale, tanto che ne abbiamo comprati tre!

    "In famiglia ne abbiamo uno ciascuno e siamo tutti molto soddisfatti. Lo zaino Flex di Airback è bello, comodissimo e sorprendentemente capiente, soprattutto grazie all’ottimo scomparto a compressione, che permette di organizzare al meglio le cose e sfruttare ogni centimetro di spazio. Della nuova versione apprezzo particolarmente il manico del trolley, finalmente più lungo e quindi ancora più comodo da utilizzare. Anche le finiture sono curate e i materiali sono di ottima qualità, con una bella sensazione di solidità e attenzione ai dettagli. Un prodotto che unisce estetica, praticità e funzionalità, perfetto per viaggiare senza rinunciare alla comodità. Promosso a pieni voti: consigliatissimo!"

    Great concept

    "The idea of creating an air compressed bag designed to fit under an airplane seat is an excellent one. The mistake I made was that the air compression was going to be magical. It does conserve some space, but not an appreciable amount. The bag is perfect for a long weekend (or maybe a week in a tropical climate where you’ll be wearing thin clothing). It predictably doesn’t hold as many cold-weather clothes as you might want for a long trip. But what separates Airback is their customer service. The first bag they sent me, the interior zipper was broken - did not zip, right out the gate. I got the bag as a “reward” on Kickstarter, not a straight purchase, so I wasn’t sure what duty Airback had to attend to the issue. Whatever their responsibility might have been, they jumped to action when I let them know the issue and acted immediately after I supplied them with photographic evidence of the damage. I very much respect their commitment, to the quality of their product and to their customers. And for that, I’m very happy to be a patron."
