Just curious, it seems that even in southern california in the summer months, those doing triathlons are almost always wearing these full body wetsuits. I would think that would be more cumbersome, but evidently not?? Do you prefer wetsuits and why? Do you actually prefer the full sleeved versions? Any particular brands? Finally, (if your a serial triathlete do you insist upon a category 5 or high end wetsuit, or is a 2-3 more than suitable?
