This is an instructional video on how to remove the jacket of a Smooth / Open cell G & Sea wetsuit.
DISCLAIMER: This is a how to, you need to take great care with your smooth / open cell wetsuit because it is very sensitive, if you rip your suit trying this I and we as G&Sea are not to be held responsible. Try this with a friend first that can assist you in case you get stuck.
That said, if you've used plenty of soap (shower gel, not conditioner!) while donning the suit, this method should work very well.
This method works well with lycra / open cell wetsuits too.
