Coolcaa paddle boards have been tested by Land Rover with great success and Coolcaa has always been extremely strict about the quality of its paddle boards. Compared to the two-layer PVC paddle boards available on the market Coolcaa uses a three-layer PVC material, which makes the Coolcaa Paddle Board more resistant to pressure, sturdiness and abrasion. In addition, each paddle board has to be checked and inflated repeatedly before it can be packed.It is especially important to note that our test was done on the road, where the road surface is very rough, and the friction of the car over the paddleboard is very serious, and there is no one else on the market that does this. They are all tested on smooth ground. That's why our paddleboards are more wear-resistant.
