Fully waterproof, this backpack has so many features it’s hard to list them all. It has a wet pocket at the bottom, a water bottle pocket at the side and two main compartments. One compartment is very large and can hold jackets etc.. The other is a padded laptop compartment with multiple pockets, some that are zippered, it has padded straps and a ventilated back plate along with a back secret pocket. This backpack has never been used. It was ordered by my husband, but did not work out for his trip.
