Yes! The Carry-on Backpack has been design to be water resistant.
The exterior fabric of the bag is made from 1680 denier luggage fabric with tight stitching and sealed polyurethane. This dramatically helps keep rain and moisture out and will resist water penetration.
In addition, all of our backpacks come with nylon elastic rain covers for an extra level of protection. The elastic rain cover is design to cover the entire top, sides, and front of the bag when worn as a backpack.
