Expandable Anti-Scratch Laptop Backpack (YT-02143) is a ready-made shelf style that grows with the trip: one expansion zip takes it from about 30 litres for the daily commute to about 41 litres for a weekend away. It fits a laptop up to 15 inches, comes in black and grey, and from 1,000 pieces we rebuild it with your logo, colours, lining and trim. Ask by style code and prices come back the same day.
A commuter backpack that also packs for an overnight trip covers two product lines with one pattern, which is why this style sells into business-travel and corporate-gift programmes. The PU face-coated polyester Oxford wipes clean and sheds light rain, the trolley strap rides on a suitcase handle, the external USB port routes a power-bank cable to the outside, and a reflective strip on the front pocket shows up in headlights. Logo positions: front panel, puller tab, straps and lining.
Open the expansion zip around the body and the depth grows from 11 cm to 16 cm — room for a change of clothes on an overnight trip.
The front panel opens wide, with a padded sleeve for a laptop up to 15 inches, an elastic strap to hold it, and slip pockets for a power bank, phone and cables.

A second compartment holds documents, a tablet or a magazine, with a pen and card panel behind it.

An upper pocket for a phone, and a lower pocket for keys, a watch and small items.

A built-in cable runs from an inside pocket to an outside port, so a phone charges from your power bank on the move. Power bank not included.

A zip pocket against the back panel keeps a passport or wallet out of reach, and the shoulder straps are padded with breathable air mesh.

Slides over a suitcase handle so the bag rides on your luggage through the airport.

A reflective strip on the front pocket and on the puller tab catches headlights on a night commute.

A thick, padded grab handle for carrying it by hand.

Strong buckles set the strap length to the wearer.

Two-way plated metal pullers that run smoothly.

The strap joins are bar-tacked to carry a full load.

One expansion zip takes the depth from 11 cm to 16 cm, about 30 litres to about 41 litres. It fits a laptop up to 15 inches, and your logo can go on the front panel, puller tab, straps or lining.
It is water-resistant: the PU face-coated polyester Oxford sheds light rain and wipes clean, but the seams are sewn. For fully waterproof builds, ask about our RF-welded styles.
