yes, Kokotat is reliable and friendly. The area is.
I have a Koko GoreTex skirt because I began kayaking in Florida during summer on Florida Bay: 85 n up. Then I went to the San Juans where the weather was cold, rainy...sometimes but then Haro Strait weather would go Caicos Bahamas HOT.
GoreTex breathes and you are comfortable. Well, you are more comfortable than nylon or vinyl: 100%. Worth the ticket ? YES !
Big deal is allowing cockpit breathing and body breathing...with the Gore suit of course. The combo produces an environment for effective layering or no layering under the suit. Still potential for inaccurate weather clothing predictions but gross blunders are minimized in a balancing environment.
I would not use the 2006 Gore Koko skirt for primary surf practice tho using the Gore Koko as an accomplished surfer is possible, use able when surf begins and ends the day.
But hammering the technique is best with a white water skirt. Reducing water dump time is essential.
