The IPC, "which is intended to replace the fireman's carry, allows you to carry an injured or otherwise incapacitated person comfortably like a backpack. Designed by Agilite in conjunction with Israeli Army Special Forces, the IPC allows the wearer to evacuate a wounded person and keep their hands free to operate a weapon or navigate difficult terrain." It’s not limited to the military. Perfect for hiking trips or any sort of situation that might require you to carry someone who is injured or incapacitated. It is $80, good idea!
