This 3D-printed and cc-machined prone double water bottle cage comes with two adjustable double bottle holders, tool-less mounting screw, and a mount for your watch. You can adjust this double bottle holder to whatever height and angle you would like. The watch holder is removable. This has more options and we feel is better than the Coastal Eddy bottle holder.
This prone double water bottle cage fits into the fin box on the deck of a prone board. The tool-less fin screw allows you to easily remove or change the position.
This works with most all water bottles.
