Porta Brace BK-3BEXP Extreme Modular Backpack Main Compartment
The BK-3BEXP is the core of Porta Brace's modular backpack system. Its main compartment is built around a padded hollow-core plastic frame that can be oriented vertically or horizontally depending on how your camera package packs, so one shell covers more than one shooting configuration.
The Extreme version ships with ultra-comfortable straps intended for long hikes and remote shooting locations. From there the pack is built out to fit the job: pair the main compartment and harness with any combination of the modular add-ons, including the 2-pocket front, the laptop pocket, the battery module and the tripod quiver. Modules are sold separately.
