If you’ve ever been stung by Ryanair’s cabin bag fees, you know how ruthless their 40x20x25cm underseat limit is. Step a centimetre over, and you’re often paying £30–£44 extra at the gate.
Right now, Amazon has this xlodea 40x20x25cm backpack designed to max out that allowance — and it’s down to £16.95 with a £4 voucher (just tick the little box).
Important: When you first click through you will see the price listed at £21.95 – that’s before you tick the voucher code box and add to basket. Then the lower price will show when you go to your basket.

Why it’s worth grabbing
- Built for Ryanair’s 40x20x25cm free underseat allowance — fits perfectly
- USB charging port — thread your power bank inside and charge your phone on the go
- Anti-theft sleeve — slides securely over your suitcase handle if you’re checking a bag
- Lightweight but surprisingly roomy — good for a weekend trip
- 4.6/5 stars from nearly 1000 reviews — rare for a bag at this price
- Works for other airlines too — fits the small bag allowance on easyJet, Jet2, TUI, and BA
The value here
- Ryanair’s bag fee starts at £6 each way online but jumps to £30–£44 at the gate
- One return trip with this bag saves you more than the purchase price
- Comparable Ryanair-specific bags sell for £25+ elsewhere
Our take
This hits the sweet spot — big enough to be useful, small enough to avoid Ryanair fees, and cheap enough that it pays for itself on your first trip. The USB port and anti-theft sleeve are nice touches you don’t usually see at this price.
