Why we don't suggest choose all black color for SUP making?
The reason is explosion.
Compared to other colors, deep black color could absorb more heat and increase pressure itslef slowly under the sun. Once you put board out of the water, the explosion risk will inrease very fast.
One of our customer feedback this problem for us before. His board is all black and double layers. when sup out of water, during they drink ice coke, the board explosion.
So for safty consideration, we suggest customer choose bright colors in single or MSL layer when design a SUP.
Thx for your time,
