We believe this will be the best backpack you will ever own. The quality will show through comfort and durability. Made with waterproof material, this backpack is super comfortable to wear with well designed (and removable) hip straps to reduce the stress of weight. Also important to us is how many well-placed pockets there are. There are seven external zipper pockets, four internal zipper pockets, and six internal non-zipper pockets. There are also covered holes on both sides at the top of the pack for hydration bladder tubes. Did we mention the all-important MOLLE system straps to be able to add on compatible pouches and accessories?
