Interestingly, I wore a wetsuit for the first time in a few months while surfing yesterday. It was a new hyperstretch suit (5-4-3mm), however, I have to say, the Predator wins. I thought that the legs might have a bit more flex in a wetsuit—that was just not the case. Paddling was definately better in the Predator. As for getting back into the wet wetsuit for the 2nd session, the predator wins this one 100%.
So, the Predator is:
Less restrictive on movement
More adaptable to different water and air temps.
