What to know before buying

Listing details to confirm

The title and specification fields list 40 × 30 × 20 cm, while the feature text also claims fit in both underseat spaces and overhead bins and compatibility with several airlines. These are listing claims, not a guarantee of acceptance. Check the selected airline's current allowance and measure the packed bag, as overfilling can affect its dimensions.

Who is it for?

A good fit for

Travellers seeking a compact backpack for short breaks or budget-airline trips.
Buyers who want a dedicated laptop sleeve and several separate storage pockets.

Less suited to

People who need a confirmed fit for a laptop larger than the listed 15-inch maximum.
Travellers needing verified waterproof protection rather than the stated water-repellent finish.

Frequently asked questions

What size and capacity does the listing give?

It lists a capacity of 24 litres and dimensions of 20D x 30W x 40H centimetres, also presented in the title as 40x30x20.

What laptop size is it listed to fit?

The compatible device size maximum is listed as 15 Inches. The listing also describes a separate padded laptop sleeve.

Is the backpack waterproof?

No waterproof rating is supplied. The listing calls it water repellent and describes protection from light rain or spills, so it should not be treated as waterproof.

Does it fit every airline's underseat allowance?

The listing claims compatibility with named airlines, but acceptance depends on each airline's current rules and the bag's packed dimensions. Check the applicable allowance before travel.
