O'Neill HyperFreak 2mm Short Sleeve Chest Zip Wetsuit Best there is Review by bill bill
The stretch and flex of this suit is truly the best i've ever worn. I don't know that it will be as durable as other suits (due to just how stretchy it is) but day in day out, it's the best flex and performance there is.

Really easy to get into. The techno butter 3 is sooooooo stretchy! Almost feels like you are naked once you get it on. Looking forward to using this suit a lot more in the San Diego spring/summer.
