everything that Kylie said is 100% right on, and if the water is cold enough that you need a wetsuit then it doesn't matter how much they cost, you need one or you can't race. Some places will let you rent wetsuits and ifyou decide to buy then they put that money toward buying a suit (a good option). About trisuits, I'd say it's a must have (one or two piece, I don't care). I'd get the trisuit first. if that means you don't have a wetsuit for a race or two then so be it (but you might have to skip the race).

Thanks a lot. I will be looking at both wetsuits and speedsuits and see how much different it is. it looks like wetsuits are very expensive if I want both top and bottom (>$300) so renting it might be worth it for the moment.

Orca are decent wetsuits IF they fit you. Definitely go to the store and try them on. Since they are used rental wetsuits, the store should probably let you take a couple to the pool.

Wetsuits should fit very tight when dry, and loosen up slightly once you are in the water. You don't want bagging of material at the armpits or small of your back. Once in the pool, some water should get in the suit. But if water is freely gushing in, the suit is likely too big.

When you try them on: 1. put bodyglide around your ankles, wrists, behind your knees and on your neck. Put on the suit one leg at a time and pull it as high and tight as you can up your waist before putting your arms in (it should fit snug to the crotch). Work the sleeves gently up to maximize room in the shoulders. DO NOT use your fingernails for any of this because you can gouge the suit easily. You may need a buddy to pull up the zipper, depending on fit/flexibility. To remove the suit, pull the zipper down and roll it off your arms, torso and legs (the suit should be inside-out once it is off).

Things to look for with a used suit: Avoid suits that are ripped or gouged. Make sure the zipper moves freely.
