The gray, water-resistant Parallax Camera Backpack from Mountainsmith holds three DSLRs, a 70-200mm f/2.8 lens, four additional lenses, a flash and accessories, and features three access points from which to retrieve your gear. First, there is the main camera gear compartment accessible from the back, then a top zippered compartment for access to a DSLR and lens, and finally a side panel that features quick-access to an interior chest-mount camera case. The camera case holds a DSLR and lens and deploys to secure to the shoulder straps at your front for fast, continuous access.
The backpack features a front zippered compartment that holds a 17" laptop behind a padded divider and a tablet inside an additional slip pocket. For small accessories, there are two zip pouches at the front and one at the side. Another side has a slip pocket that unzips at the bottom to accommodate a tripod leg, and a compression strap at the top that holds down the tripod.
To carry the backpack, there are padded, adjustable dual-density shoulder straps with load lifter suspension and padded waist straps. For storing small accessories, there is a mesh slip pocket on one waist strap, and a zippered pouch on the other. For comfort while wearing the backpack, an Anvil Airway Suspension system is built into the back and consists of an ergonomic padding that allows air to circulate against your back. A sternum strap provides further comfort for carrying a heavy load, and a grip handle at the top allows you to grab your bag and go.
