What They Say About Airback

The Design Process



Since October 2023, we’ve been building a community that believes travel should be easy, smart, and fee-free. When we set out to design FLEX, we had one clear mission: create the ultimate travel bag. A bag that solves the everyday problems travelers face, from costly baggage fees to fragile luggage that doesn’t last. FLEX was built to be smarter, stronger, and more adaptable, so every journey becomes easier, lighter, and more enjoyable.

Intelligent by Design
Form follows function. FLEX carries the timeless, minimal look of the Airback Family, a design language travelers already love and trust. We built on proven concepts that excited our community, keeping the clean elegance and purposeful details that make Airback unique. At the same time, we pushed further: making FLEX even smarter, refining every feature, and improving wherever we saw the chance.

A perfect showcase of design innovation: the compression bag is engineered with precision to integrate seamlessly around the aluminum handle frame, making use of every single inch of space. Nothing is wasted, and every detail is engineered to maximize efficiency while keeping the sleek Airback aesthetic.

Comfort & Flexibility


Airback FLEX is designed to move seamlessly with you. Despite its strength, it feels light and effortless to handle, with smooth-rolling wheels, an ergonomic grip, and perfectly balanced weight distribution that reduce travel strain. Just as important, it offers speed and convenience, with fast, easy access at airport security and customs, making every journey smoother.

We set out with a revolutionary goal: to redefine travel by placing the perfect trolley in one hand and the perfect backpack in the other. In backpack mode, FLEX carries forward the very best of our proven Airback designs. The specially engineered structured padding ensures ultimate comfort, so wearing FLEX feels just as natural and convenient as our dedicated backpacks. We also integrated ultra-strong coated buckles and other smart Airback innovations to guarantee reliability and ease of use.

In trolley mode, we tackled a new challenge: achieving maximum strength while keeping the product as lightweight as possible. The result is a cleverly engineered framework that offers flexibility without compromise, light to carry yet strong enough to handle loads of up to 23 kg with ease.

Durability & Sustainability
FLEX is engineered to last, not just for a season but for a lifetime of travel. Built on the strength of aerospace-grade aluminum and rugged all-terrain wheels, it’s designed to withstand the demands of modern journeys without compromise. True durability goes beyond strength; it’s about materials that endure, protect, and perform trip after trip.

That’s why every component of FLEX has been carefully chosen:

Trusted Partnerships, Built to Last
At Airback, we believe the perfect product begins with the right partnerships. That’s why we work only with suppliers who share our vision and values, partners we’ve trusted from the very beginning. These relationships go back to our very first prototypes, and we continue to grow, learn, and innovate together.

We don’t just collaborate remotely; we often visit our suppliers in person to ensure our high standards are consistently met. These visits strengthen our partnerships and ensure that every production run lives up to the Airback name. Alongside this, we work with an independent QC team who guarantees that every single bag undergoes a 100% quality check before it reaches you.

Every material, every stitch, and every component of FLEX is tested again and again by our Airback teams to deliver unmatched performance. Nothing is left to chance.
For us, suppliers are not just vendors; they are part of the Airback Family. Together, we push boundaries, uphold integrity, and set new benchmarks for what travel gear should be.
