The Wheeled Kit Bag 40L and the Travel Backpack 40L are both ideal for 3-5 day trips. Each one is carry-on friendly, sustainably made and constructed with smart features for real travel. Whether you roll or carry, these cabin-ready travel bags are built to perform.

The question is which one is right for you... Wheeled Kit Bag 40L or Travel Backpack 40L?

SIMILAR SIZES, DIFFERENT SHAPES

While both bags offer a 40L capacity and are designed to meet most airline cabin size restrictions, how they carry and how they pack sets them apart:

  • Wheeled Kit Bag 40L: has a more structured, rectangular shape with a rigid base. Designed to roll, it offers a boxier form that stands upright and holds its shape, making packing simple and organised.
  • Travel Backpack 40L: has a softer, more contoured profile that moves with your body. Its flexible form and clamshell design make it ideal for wearing comfortably while still giving you full access to the contents.

Airline Carry-On Compatibility

Both the Wheeled Kit Bag 40L and Travel Backpack 40L meet most airlines’ cabin size requirements—but it's always worth checking the specifics before you fly.

Fits Most Major Airlines

With dimensions of 55 x 35 x 23cm for the Wheeled Kit Bag 40L and 55 x 35 x 20cm for the Travel Backpack 40L, these bags are compliant with the majority of full-service airlines, including:

  • British Airways
  • EasyJet
  • Lufthansa
  • Air France
  • KLM
  • Virgin Atlantic
  • American Airlines
  • United Airlines

The Travel Backpack 40L is also accepted on airlines like Emirates and Qatar Airways thanks to its slimmer profile.

For budget airlines

Budget airlines such as Ryanair and Wizz Air have stricter cabin size limits. The Wheeled Kit Bag 40L is likely to exceed their standard free carry-on allowance, while the Travel Backpack 40L may still be permitted if you've booked priority boarding or an additional cabin bag.

Tip: Always check the carry-on policy of your airline before travelling and read our article on how to navigate the ever-changing airline luggage policies. Some require you to factor in wheels and handles in the measurements.
