It is highly likely that wetsuits will not be allowed in my next 70.3 Ironman because of water temperatures. I have never raced in the open water without a wetsuit. What are my options? Is there anything (i.e. trisuit) that will give me some buoyancy or flotation?
Rocket Science Sports make a race suit that they claim has slightly positive bouyancy that is just under the legal limit set by USTA for non-wetsuit TRIs

I haven't used one or know anybody that has. This is the only one that I have seen that claims to provide some bouyancy.
