Advanced Elements DropStitch floor for AdvancedFrame 1

The high-pressure air bottom familiar from SUP boards is available for the Advanced Elements AdvancedFrame unit kayak. The DropStich bottom stiffens the entire structure of the kayak, improving its glide and directional stability in the water. The DropStich inner bottom is about 5cm thick, and it becomes so hard that it is even possible to stand on it in the kayak. The DropStich bottom does not need to be removed separately when the kayak is assembled, but can be folded into a bag with the kayak. The valve is different from the one in the kayak.
The DropStich insole replaces the Advanced Elements Backbone stiffener. If you use the DropStich insole, you cannot use the Backbone.
