What to look for in a slim laptop backpack
- The right laptop compartment: a bag rated for 15.6 inches usually fits laptops up to 16 inches. Look for good padding on all sides.
- A shallow depth: around 10 to 13 cm keeps the bag close to your back and easy to carry on crowded trains.
- Water-repellent fabric: protection from rain and splashes for your laptop and papers.
- A light empty weight: about 600 to 800 g is comfortable for daily use.
- Just enough organization: a tablet sleeve and a few inner pockets, without bulk.

A note on "waterproof"
Most slim laptop backpacks, including these, are water-repellent or water-resistant rather than fully waterproof. That keeps your laptop dry in everyday rain, but not if the bag is soaked for a long time. Read the difference between waterproof and weatherproof for more.
