The Dual Cylinder system combined with the Hi Flo handle means you are in complete control of the time and energy required to inflate your board. It puts the volume into your board faster and reduces the effort required to reach a higher pressure. A revolution in pumping technology! A fantastic upgrade for any inflatable board, it allows you to pump your Red Paddle Co board to 20psi in the fastest time using less energy! And for 2017, it’s been totally redesigned to be more efficient – less pumping, more paddling
