What to know before buying

Listing details to confirm

Listing details conflict: the title states 24L while the details give 20 Liters, and dimensions are variously stated as 20D x 25W x 40H centimetres, 40 x 20 x 25 cm and 40cm*30cm*20cm. Feature text also lists a 1KG weight, while item details give 0.71 Kilograms. Confirm the selected listing’s dimensions, capacity and weight before purchase, especially for airline baggage limits. The waterproof rating is a listing claim, not a stated test result.

Who is it for?

A good fit for

Travellers wanting a backpack with separate shoe storage, a wet pocket and multiple organising compartments.
People carrying a laptop up to the listed 14-inch maximum who want a bag described with a padded shoulder harness.
Short-trip users who want a rear strap to attach the bag to rolling luggage.

Less suited to

Buyers who need a reliably confirmed capacity or dimensions for a strict airline baggage allowance without first checking the selected listing.
People seeking a documented durability guarantee or independently established water protection.

For buyers considering it as compact airline luggage, the positive travel feedback is relevant, but it does not resolve the listing’s conflicting size and capacity details.

Frequently asked questions

What size is this backpack?

The listing gives different measurements: 20D x 25W x 40H centimetres, 40 x 20 x 25 cm and 40cm*30cm*20cm. Confirm the exact selected variant before relying on the dimensions.

Is the capacity 20 or 24 litres?

Both figures appear in the listing. The title says 24L, while the item details state 20 Liters, so the actual capacity is unconfirmed.

Yes. The title and feature text describe a separate shoe compartment, alongside a wet pocket.

What size laptop does it fit?

The listing states a maximum compatible device size of 14 Inches and describes a laptop compartment for a 14-inch laptop. Fit may depend on the device’s dimensions.
