what is the waterproof travel Backpack

A bag can be called waterproof dry backpack only if it doesn't allow entry of moisture into its compartments when submerged in water. Some pricier bags are fully made from waterproof material including waterproof zippers, however, many bags are just water resistant, not totally waterproof. When choosing a waterproof backpack, find out about its submersion and the material used in its construction. IPX6 rating, 
for example, means that a bag has the highest level of dust protection and can stand up to low-pressure water jets; IPX6 rating means the bag is protected against dust and strong jets of water and is briefly submersible; IPX7 rating means the dry backpack is truly waterproof and can be submerged for longer periods.

All in all, this waterproof travel backpack is unmatched in features and will definitely make your outdoor journey comfortable. It’s lightweight so you can carry it wherever you go.
