Wetsuits

Ok, since Marty's Old School Aquathon Series kicks off tomorrow, I figured I'd post something semi-on-topic. These three websites (onetri.com, beginnertriathlete.com, and triathlonsuit.org) are pretty comprehensive, discussing everything from why you would want a wetsuit to how to select one that best meats your needs. So, to summarize the "why":

• Wetsuits make you faster. The added buoyancy places your body higher in the water, which helps to reduce drag. Not only does this mean that you don't have to work as hard, but it also promotes better form. Additionally, wetsuits increase hydrodynamacy (I'm an engineer, I'm allowed to modify words to fit my need)... think of all the world records that were broken with those crazy Speedo suits back in 2008.
• Wetsuits provide protection and keep you warm in freezing cold water.
• Wetsuits make you look intimidating... the arm warmers and compression socks of swimming! I mean, just look at the "superhero triathletes" in that picture... is the the 'X' for X-Men or Xterra?!? I'm sorry, I know I'm mixing "superheros" here (very un-engineer of me), but... "Swim, Bike, Run, Transition... by your powers combined..." :-)

Ok, on to selection. There are four major things to consider: comfort, price, fabric, and durability. First and foremost, make sure the suit fits you properly... try it on before you buy it if at all possible (if ordering online, try to get to a store that carries the suit, or consider renting before buying). Make sure that it is not too loose (it should feel snug... in fact, many people find "performance fit" to feel too snug), and that the neck and wrist "seal" is good (to prevent water from flowing into the suit). It's ok if the arms and legs are a little short, just make sure that your stroke and kick are not restricted. Comfort is also related to the buoyancy and flexibility, which usually comes with an increased price tag. However, the last thing you want to be thinking about on the swim is how uncomfortable your suit is, and how this could have been avoided if you just bit the bullet and spent an extra $XX. In terms of style, probably the biggest choice you'll have to make is sleeved vs. sleeveless. If the majority of your swimming is in relatively warm water (70 +/- a few degrees), then you'll probably want a sleeveless suit so you don't overheat. However, if you want to be a polar bear, do not despair... it's a myth that full-sleeved suits reduce flexibility. Another thing to consider is full-leg or short style, although most of the suits I've seen are full-leg (I'm assuming because they are more hydrodynamic). Some manufacturers are also starting to offer two-piece wetsuits (versus the more traditional one-piece suit with a zipper up the back) to allow wearers to mix-and-match sizes.

And last, but not least, here is a list of USAT-approved wetsuits, and the link for the current USAT rules.
