Laptop Backpack for 17.3 Inch Devices

This backpack holds laptops up to 17.3 inches in a padded compartment and expands from 35 to 40 litres for trips lasting three to seven days. It weighs 2.5 pounds and is made from waterproof polyester with anti-theft back zipper pocket, durable explosion-proof zippers, a wet-dry compartment and two included toiletry bags.

Travel-Focused Users Seeking Carry-On Convenience

Suits travellers who want an airline-approved personal item that opens 90 to 180 degrees for quick security checks and fits under the seat. The shoulder straps tuck away for briefcase-style carry and a luggage strap secures it to a suitcase. Not for buyers who need a framed hiking pack with hip belt or a dedicated camera organisation system.

Expandable 35-to-40-Litre Capacity

The single specification that decides fit is the expandable volume range of 35 to 40 litres combined with the 17.3-inch laptop sleeve. If your gear exceeds 40 litres or your laptop is larger than 17.3 inches, this backpack will not accommodate it.

Questions about this item

Will the 17.3 inch laptop compartment still close properly when the main section is expanded from 35L to 40L?

Yes, the padded laptop sleeve is separate from the expandable main compartment, so a 17.3 inch laptop fits and the bag zips shut at either capacity.

How can I verify the backpack meets airline personal-item dimensions after I pack it?

The bag is designed to the maximum allowed size; once packed, check that it fits under the seat and that the main compartment opens 90–180 degrees for security screening.

Does the package include a power bank or charging cable for the external USB port?

No, the side port is a pass-through only; you must supply your own power bank and cable. The box contains the backpack, two toiletry bags and a luggage strap.
