This black Lowepro FreeLine Backpack 350 AW is a versatile bag that features two primary configurations. Inside its spacious main compartment, a removable, folding partition system forms three shelves that can be used to store camera, video, audio, or digital media equipment. The shelves can accommodate a DSLR camera kit with a 70-200mm f/2.8 lens, and to enhance the ability to organize the contents, a Lowepro Gear Box equipment pouch is included. Cords, adapters, and other essentials for the devices carried by the FreeLine Backpack 350 AW can be inserted within the Gear Box, keeping them organized and available. Complete access to the FreeLine Backpack 350 AW's interior is enabled by a zippered rear panel, while two zippered side openings further complement the folding partition system and Gear Box. While in use, the folding partition system's shelves and the Gear Box itself can be reached when the bag is rotated from one's back to front with either side opening facing upward. Each side opening also provides interior organizational pockets for memory cards, batteries, or other accessories that are frequently exchanged when an item is removed or placed within a bag. When the FreeLine Backpack 350 AW is worn, a dedicated compartment for 15" laptops rests directly behind the shoulders, followed by the main compartment, and a front-facing pocket for items that need to be accessed quickly and conveniently, such as a pair of sunglasses or music player earphones. Positioned above the backpack's base, the laptop compartment helps minimize the effect of any bumps or shocks upon its contents. Along the exterior of each zippered side opening is a large, open pocket that can hold a water bottle, tripod, monopod, or trekking pole; any one of which can be secured using a locking strap above each pocket. The FreeLine Backpack 350 AW can be carried using its built-in top handle, or by its adjustable shoulder straps. A zipper along the inner edge of the strap which rests over the wearer's left shoulder opens to reveal a pull-out smartphone pocket that accommodates even large-screen mobile devices. When traveling over difficult or uneven terrain, the bag's waist belt transfers weight to the hips for additional comfort, while the sternum strap further limits unintentional shifting around the wearer. Featuring durable, weather-resistant nylon construction, this backpack's attachment webbings along its sides and on the face of its front panel allow for pouches with external straps such as the Gear Box to be clipped or tied to this bag's surface. While traveling with a rolling case that features a dual-column telescoping handle, a pass-through band across the center of the FreeLine Backpack 350 AW's rear panel allows this bag to be mounted onto such handles for added convenience.
