Hauling dive gear through an airport, dragging it across a hotel lobby, and hiking it on a half mile trail to your dive location has never been easier with the Aqua Lung Defense Pack. The backpack straps feature an ergonomic shape and 3D mesh for added padding. All the seams on this bag are heat welded and waterproof. If you need more room or a spare dry compartment, the loop on the front of the bag is used to hang the smaller Aqua Lung Defense Bag.
