Pros and cons

Pros

The stated 0.7 kg weight keeps the empty bag relatively light for a cabin backpack.
A laptop compartment and six listed pockets provide separated storage for travel essentials.
The claimed 180° opening may make it easier to lay the bag open for packing or security checks.

Cons

The listing does not give the laptop compartment's supported device size, so buyers should compare it with their laptop dimensions.

What to know before buying

The listing claims compatibility with Ryanair and other airlines, but airline cabin-bag rules can vary. Check the current allowance for your specific fare and flight, and measure the packed bag.
The cable hole is for charging with your own power bank and cable. The listing explicitly says those items are not included. The described wet-item pocket is not separately itemised in a supplied package inventory.

Listing details to confirm

The listing details are inconsistent: it gives a 24-litre volume while the model number contains “30L”, and the colour field says Green while the model number says Smoke Green. It also gives 40 x 30 x 20 cm but warns of a 2–3 cm manual-measurement error. Confirm the selected bag's dimensions, capacity and colour before relying on airline fit.

Who is it for?

A good fit for

Travellers seeking a lightweight backpack listed at 40 x 30 x 20 cm for cabin or under-seat use.
Buyers who want a laptop compartment, multiple pockets and a separate place for small wet items.
People who prefer a backpack with padded shoulder straps for carrying through an airport.

Less suited to

Buyers who need a verified laptop size, confirmed water-tight protection or an independently established airline fit.
Those who need a confirmed capacity of exactly 24 or 30 litres without checking the discrepancy.

Customer feedback highlights perceived roominess, useful pockets, comfort and under-seat usefulness, including on EasyJet flights.

Negative themes

Some customers report straps breaking after one trip.
