How about layering a 3mm back zip shorty over your Flexa 3.2.2 instead of getting a 5mm? It will be as warm or warmer than a 5mm and it's a lot easier to find a shorty that fits. Plus you'll have 2 options if the water is warmer than you expected and you'll save a few bucks.I bought a new Mares Flexa 3.2.2 wetsuit online. Front zip.... I like the suit so much I am thinking about buying a 5mm.
Any ideas?
