Are the backpacks suitable for air travel as cabin luggage?

Many of our backpacks meet the requirements, but this depends on the model and size. The PeakStone Backpack in Small and Medium, the MountainRock Backpack in Small, and the Dachshund Mini (S) meet the requirements for approved transport containers for many airlines. Larger models such as the MountainRock Large or the ROOFPACKER are usually too big. It is essential to check this with your airline in advance, as guidelines and regulations can change regularly.
