Tradeoffs we can infer

Published dimensions do not include wheels or handles; leave extra real-world margin before relying on a tight airline fit.
Do not assume packed corners, pockets, or bulging fabric stay inside the listed rectangular dimensions.
Manufacturer-published with high confidence is strong enough for comparison, but variant naming still matters at checkout.

Buyer risk notes

Within comparable laptop backpack bags in this catalog, capacity is 1 L above the category median (24 L); empty weight is 0.3 lb below the category median (2.4 lb).
Gregory and Amazon routes are attached; verify the exact model and colorway because collection-level merchant pages can mix nearby variants.
