Metz Stowaway 20L Travel Bag 16x10x8inch (40x25x20cm) - Mini Backpack/Weekender Bag Ideal Underseat Carry on Luggage (Navajo Blue)

If You're flying on Ryanair. These bags can be helpful because of the bag restrictions on airlines like Ryanair. The bed comes with I believe a 5-year warranty which led me to believe that it was very durable. However, even moderately loaded bag ripped on our first trip. When I tried to reach out to the company they didn't honor the warranty. The company is based in Britain I believe so that influences warranty support. It's a decent bag, well designed well, laid out and fits all the requirements for the no frills airlines. Just wish they would have put more effort into better sewn seams and stronger material. We bought three of these and only one ripped so maybe that's a good sign. The bag can become a backpack though. Not a comfortable one, but for short walks it's okay
