Our take on the adidas Expandable Backpack

The adidas Expandable Backpack is an 18-liter zip-top daypack with a water-resistant shell and a main compartment that unzips to add extra room when you need it. It is a simple, solid-color design with few pockets, so it suits commuters, gym-goers and light travelers who want a clean look and a bag that grows for a grocery stop or an overnight. Against padded laptop backpacks from adidas and its rivals, it trades organization and structure for lighter weight and flexibility. Buyers rate it highly, though with only 19 ratings the feedback is thin.

Questions and answers

How much does the expandable section add?
The pack is 18 liters closed. The expansion zipper adds depth to the main compartment rather than a second pocket, so the extra room is best for soft items like clothing or groceries.
Is it waterproof or just water resistant?
The listing calls it waterproof and water resistant. Treat it as water resistant: it sheds rain, but seams and the zipper are not sealed for submersion.
Does it fit a laptop?
There is no padded laptop sleeve. A slim 13-inch laptop can sit in the main compartment, but it gets no separate protection or suspension.
Is it good for a carry-on?
At 18 liters it fits under most seats and in overhead bins, and expanding it helps for a short trip. It is not a full travel pack with load-lifting straps.
What colors are available?
It comes in black, brown and blanch cargo, all in a solid-color finish.
Is it suitable for the gym?
Yes for shoes, a towel and a change of clothes. There is no ventilated shoe compartment, so damp gear shares the main space.

At eBay, for $19.00, 65% under what the other stores charge, as of our latest check.
