I have been using a fs-pro size M/L, but I bought a new one at the Coral Springs Swim Center store, size M (without the L), following the orientation of the store manager who insisted that it was the proper size for me. I will try this new one at the nationals in Austin...<div style="clear:both;"></div>https://community.usms.org/thread/89789?ContentTypeID=1Tue, 18 Mar 2008 08:56:47 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:e8ea936c-bdf6-41b3-a094-6be17e1fbf43Former MemberI&#39;m pretty close to your size: 6&#39;1&quot; with 32&quot; waist and just bought an FS-Pro size L/L. This was after discussing sizing with the seller who seemed pretty knowledgeable. He felt I needed to go a little bigger than my FS II which is an M/L. I tried it on at home and it took me a struggling 10 minutes (which seemed much longer due to my wife&#39;s hysterical laughter) to get it on. I won&#39;t try it the water till nationals. I&#39;m still bummed I can no longer get the Arena Power Skin. Best suit ever. I got mine for $260 at swim2000.com. Hope this helps.<div style="clear:both;"></div>
