How Waterproof Are Laptop Bags?

The water resistance of a laptop bag usually depends on its materials and design.

Waterproof materials: Some laptop bags use water-resistant materials that effectively prevent water from penetrating into the bag, making it waterproof in light rain or splashing situations. 

Sealed zippers: Some high-end laptop bags may have waterproof zippers that effectively prevent water from penetrating into the bag through the zipper gap.

Bag opening design: The design of the bag opening is also important, which can effectively prevent water from entering the bag from the top or sides.

In addition to external water resistance, some laptop bags are also equipped with internal padding or insulation to protect the computer from moisture.

Although the laptop bag may be somewhat water-resistant, it is still recommended to avoid long-term exposure to strong rain and not to fully submerge the bag in water.
