Drop-stitch technology involves joining two layers of material using thousands of nylon threads. These threads are evenly distributed throughout the material, which, when inflated, provides great rigidity. This makes the structure stiff enough that the boards can maintain a shape and hardness comparable to hard boards, even with little air pressure inside. Products made with this technology achieve properties similar to uninflated structures, which ensures high stability and durability.

SUP inflatable board construction from FANATIC. It reduces the weight of the board by approximately 25% compared to boards with standard Double Layer technology. It also provides a 30% increase in stiffness. Double Layer Light consists of two layers of PVC. The second layer is welded directly to the core and surrounds the V-Drop Stitch material. The third layer consisting of coloured side strips supports the durability and high quality construction.
