This bag is carry-on compliant with most major airlines, even though the dimensions may not be within limits. 

When designing our bags, we design for optimal proportions and desired carry traits. While we do consider airline luggage dimension rules, we don’t strictly adhere to them because soft luggage is malleable. 

For one, they all vary depending on who you’re flying with. Two, airline rules are meant to ensure bags fit into the overhead bins and under your seat on their aircraft, and as long as your soft luggage is close enough to their dimensions it will fit within the luggage size tester and the overhead bins. In our experience, airlines rarely check or measure soft luggage, and if you’ve packed the bag normally (meaning not too overstuffed), it will fit. 

As they say, your mileage may vary, but our team has traveled on hundreds of flights with our largest 50L bags (technically way over the carry-on limit), and we’ve never had a problem. If you ever do have an issue we’d love to hear about it. Happy travels!

The Cero Travel Backpack is the first bag that we developed using the Aeroweave textile. 

Aeroweave gets its name from laminating 750D Polyester yarn, laid in a “diamond grid” pattern, sandwiched between a 210D nylon ripstop face fabric and 65D polyester taffeta backing; and finished with a PFAS-free durable water-resistant coating. 

This layering technique is inspired by the way sailcloth is made, using tough, lightweight, and weather-resistant materials designed to withstand extreme, even rogue, weather conditions.

Spot clean only. Other cleaning methods may damage your bag and void the warranty. Read the full care guide  →
