BAGZY Ryanair Cabin Bag 40x30x20 Wizzair Underseat Cabin Bag, Waterproof Foldable Duffel Bag Holdall Hand Luggage Case Carry on Luggage Flight Bag Baggage Organiser Storage, 25L Nylon Grey

The BAGZY Ryanair bag is sized at 40 x 30 x 20 cm, which is Ryanair's current free underseat allowance. 25 litres. Foldable, waterproof nylon. 2,000 reviews at 4.3 stars. It costs less than a Ryanair seat selection and does what it needs to do.

The size

40 x 30 x 20 cm. Fits Ryanair's checking box without getting flagged. Also fits Wizz Air, Volotea, and most budget airlines with similar limits. For the exact measurements each airline requires, our UK airline baggage allowance guide has the full list.

If you fly easyJet too, their free allowance is bigger (45 x 36 x 20 cm). BAGZY make a separate easyJet version for that. Our Ryanair vs easyJet baggage allowance comparison explains the difference.

What fits inside

25 litres is enough for a weekend. Main compartment takes clothes. Two mesh pockets inside for small items. Wet/dry separation pocket for toiletries. Front pocket for passport and boarding pass. That's more organisation than you'd expect from a £10 duffel.

Carrying options

Shoulder strap (detachable, adjustable 66-110cm), top handle, or slide it onto a trolley handle. The shoulder strap has a padded section. It's not going to replace a backpack for comfort, but for getting through an airport and onto a plane it's fine.

Foldable

Folds flat when empty. If you're going somewhere to buy things and need the bag space on the way back, this works. Or keep it folded in a suitcase as a spare.

How it compares to the Cabin Max Metz

The Metz is a backpack. More structure, better weight distribution, laptop-friendly. The BAGZY is a duffel. Lighter, cheaper, folds flat. Different tools for different trips. Our best cabin baggage roundup compares both types.
