Bright Blue, Professional water sports' goods seller. We have our own factory is engaged in manufacturing the ISUP boards.
We have single layer, normal double layer and new double layer( we call it reinforced), normally now all the factories make the normal double layer boards, and we can make the single layer board and reinforced double layer.
Single layer, which is lighter than double layer, in order to let it have the same strength as double layer, we use the special workmanship, we call it centre stringer(a special webbing).
Normal double layer, we put one more PVC layer on the top the bottom.
Reinforced double layer, when we buy the fabric for our supplier, they attach the other layer on the raw material, which is lighter than the normal double layer, and now only Red paddle use this for the market, our supplier also have this kind of fabric to support us to make the SUP boards.
