Shootout Backpacks The flagships of the collection, Shootout Backpacks are offered in five simply-named sizes: Mini, Small, Medium, Large and Large Rolling. The size range covers every conceivable need, from day-trippers and vacationing enthusiasts to outdoor/commercial pros working on remote locations or expeditions. All sizes except the Mini include padded, frame sheet reinforced laptop compartments for computers up to 17" (depending upon backpack size). The Large and Rolling backpacks are suitable for lenses up to 400 or 500mm, depending upon specific equipment variables. All models incorporate easily customized, well-padded interiors, fully-adjustable harness/belt systems, and the fast-deploying, "Velcro-free" WeatherWrap auxiliary protection cover. The generous, padded side pockets feature interior panels that can be moved to convert the space from cargo pocket to QuickAccess interior hatches. This allows fast, easy retrieval of a lens or accessory without having to fully remove or open the entire pack. The Backpacks also feature a significant new innovation, dubbed "MSTC", for Multi-Stage Tripod Carrying system, which adjusts to securely and optimally carry tripods of varying sizes and styles. All Shootout Backpacks and Waistpacks also come complete with "attachable" accessories one a media card wallet and the other a padded pouch for phone or portable audio player. The accessory cases are secured to the packs with clip-on security tethers, but can be removed and attached to various clip-on points on Shootout waist belts and/or shoulder pads.
