Single layer and MSL fusion layer is most common paddle boards we are using.
But how to distinguish our paddle boards layers?
-1. Weight.
Single layer paddle board body normally weight 7-8KG;
MSL layer paddle board body normally weight 9-10KG;
Double layers paddle board body weight around 11-12KG;
X-woven layer paddle board weight around 7-8KG too;
-2. Stifness after inflation with pressure:
When stand on center, single layer easy deform like a banana;
MSL layer and X-woven layer performance will better;
Double layer is the best on stiffness;
-3. Pressure;
Normally we don't have chance to test this, because it's dangerous and highest pressure not only depends on drop stitch material, but also depends on sealing handworks and sealing methods.
