Operating pressure
Also: air pressure
Packrafts work with very low air pressure. Firm but not rock-hard is the goal.
Most packrafts are filled with the inflation bag and by mouth. A pump adds a little more stiffness, which large boats and whitewater paddlers appreciate. Too much pressure in blazing sun puts strain on seams and valves. Follow the instructions in your boat's manual.
