I cant imagine wearing a 3/2 heated in the winter. must be nice ...Cant wait to chuck the 5/3!
Have you ever ONCE owned anything that ran on batteries where you didn't run down the batteries from overuse, or wished they held a charge better, or forgot to charge, or didn't hold a charge in cold weather? think cell phones, cam corders, digi cams, you name it....
I wouldn't go chucking the 5/3 too fast. Backups never a bad idea.
I give Mother Nature alot of respect when it comes to cold water surfing. I spend signifacant time outside in the cold of Minnesota working and playing. I have had great times surfing in below zero air temps and 33* water. With the risks and dangers of being exposed to the extreme cold, I don't want to bank on batteries.
Ya I was read Surfing magazine a couplea months ago and read that they tested it out in antartica! I know mags sometimes strech the truth but the were diving off iceburgs into the lineup and getting slotted in head-high barrels. Meanwhile, just the thought of doing that in the wetsuit i hav now gave me brain-freeze. My guess is that this is the real deal.
