I have the Dakine zippered vest (surface vest). I have only used it for windsurfing on winter days so far. Plan on using it for SUP. FYI the sizing on this vest is odd. I have broad shoulders but I am thin. Take a mens large tall in a shirt. I tried these on in the store and ended up with XXL. I wear it on the outside of my suit, and it fits well. Extra float is nice when waterstarting and keeping your hands out of the 40 degree water.
