https://community.usms.org/swimming/f/open-water-training-and-technique/24864/warmest-non-wetsuitFor a long open water swim where wetsuits are not legal, do you think it is warmer to wear a regular suit or a fastskin full-length type suit? I&#39;m not sure if the leg coverage would provide warmth over a 2-hour swim or not. Any suggestions?

I feel like it keeps me warm if the sun is out. The silver almost seems to have an &quot;aluminum foil&quot; thermal-like quality.<div style="clear:both;"></div>
