The Portabrace PB-2750ICH is a complete protective transporting system. You can ship your rigid-frame backpack in the PB-2750E hard shell (included), then remove the interior, Packer-style soft case. 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.
