The Portabrace PB-2750ICH is a complete protective transporting system. Ship your rigid-frame case in the PB-2750E hard shell (included), then remove the interior Packer-style soft case and attatch the backpack straps. Carry over-the-shoulder or attach the padded laptop harness system and carry as a backpack. The expanded harness module includes ultra-comfortable padded straps with cross-chest clips and a padded laptop sleeve. The roomy interior and divider system allow you to keep most camera setups in “Shoot Ready” format.
