Slim Expandable Backpack with Dry-Wet Separation Pocket

Slim Expandable Backpack with Dry-Wet Separation Pocket

Slim enough to slip into a crowded commute yet expandable when packing more, this backpack separates a 15.6-inch laptop from damp gear behind a water-repellent shell.

8cm Instant Expansion: A single zipper pull grows capacity from 9L to 18L for extra packing space when needed.

Dry-Wet Separation Pocket: A dedicated compartment keeps a laptop, tablet, and phone apart from damp or bulky items.

Slim 7cm Profile: The thin, lightweight 0.88kg build stays easy to carry through tight spaces and crowded transit.

Breathable Back Panel: Ventilated padding reduces sweating on long carries, and a rear strap secures the bag to rolling luggage.

As a specialized large-capacity backpack manufacturer, we offer OEM and ODM production with custom colors, logos, and packaging for wholesale and private-label orders.
