Gore-Tex Vent Plug
This Gore-Tex Breathable Vent allows EPS core surfboards and wooden surfboards to pass air and gases back and forth between the core and the exterior of the board while preventing water from entering. This is due to the fact that EPS surfboard materials and wooden surfboards are affected by extreme temperature changes causing expansion and retraction.
The Gore-Tex microporous membrane prevents pressure build up by constantly equalizing the difference in pressure between the inside of the enclosure and its immediate environment. Instructions included.
