Triathlon / Swimming Wetsuit Rental

[segundo3000gt]

Thanks for the replies guys.  Suddha, I did a google search on your wetsuit.  It says that it's a 5mm in the front and 3mm in the back which is thicker than I would have expected a triathlon wetsuit to be.  It does talk about flexibility.  Is there something different about the neoprene used in the wetsuit that allows better flexibility than a typical dive wetsuit?  I picked up a 3/2 full at the Smith Diving garage sale last year for $20 and I was considering trying it out in the pool to see how it felt compared to swimming with no wetsuit.
