I am looking into going into triathlons and I was wondering wearing a trisuit improves your performance in triathlon.

    Personally I think "what are the advantages and disadvantages" makes an awful question. My opinion, my close vote.

    I agree with @waxeagle. This question is also a little light. An image and links to what the OP is questioning would help that.

    I don't necessarily agree with the criticisms. I actually thought it was a pretty easy question to accurately answer, even though I didn't provide any "hard" quantitative evidence to back it up. I've been a supporter at a few triathlons, which is where the inspiration for my answer came from. As for the "advantage and disadvantage" questions, they don't seem that bad when you're talking about equipment. If you're familiar with a sport, you can easily provide some good (helpful) information.

One of the advantages comes in the swimming leg. Depending on the quality of the suit, it may have less drag in the water than the normal human body, theoretically increasing your speed. Many high-end suits advertise this advantage: http://www.trisports.com/trspsu.html

As for disadvantages, I don't see many.

  • I think you are confusing trisuits with neoprene wetsuits Commented Mar 24, 2012 at 20:36
  • @solomongaby Regarding the buoyancy, you're definitely right. But, the high-end models of trisuits definitely advertise having less drag. I edited my answer above to reflect this.

I'd sum this one up as it's an advantage if it saves you time, and it's a disadvantage if it doesn't:

  • If you're uncomfortable and it rides up or leaves you constantly adjusting the fabric, then it's going to affect your times on the bike and the run even if it saves you time getting changed in the transition.
  • If you are comfortable in it, then you don't have to waste time changing clothes in transition and you're probably wearing a well fitting suit that will result in less drag so you'll be a bit faster.

I would suspect the primary benefit is time saved in transition. Usually shirts are required in races, so after the swim you have to do something to cover up. (I suppose you could wear stuff under a wetsuit, but I do not use wetsuits).

If you do not have to change anything in transition it can help. Other than that, I suspect it is comfort.


All my experience is in warm sub-tropics so NO WETSUIt swims. I imagine I'd stick with just tri shorts for wetsuit swims anyway but a tri suit under the wetsuit is sure to have some advantages.

Adv - don't have to put on a T-shirt or singlet after the swim - this takes me 3 secs and while many quibble over 3 seconds in transition I find the 3 secs gives me time to get my breath back after the swim hell.

Disadv - why part with $80 - $160 for something you wear a couple of times a year.

6 years ago, very few people were wearing tri suits. I have recently returned to the sport and think out of 60 in my age group, I and one other are not in tri suits.

Just remember, this industry is all built around money..... tt bikes, tri suits, gu's are a marketer's dreams.
