Is it made of waterproof fabric?
JOEL D No it is not made of waterproof fabric.
CHRISTOPHER J It's water resistant material so any liquids that get on the bag will not go through and will bead off
Bill P I used this backpack for almost 2 years in the Caribbean... Where there are torrential downpours all the time. Lugged my laptop and papers everywhere in it and never had an issue with leaks or water damage. Short of submerging the pack underwater, I think this bag will keep your stuff dry even under tropical storm conditions.
