Some users think it’s just not enough padding for a full Iron Man triathlon.

The fabric dries quickly and is ultra-light while providing UPF 50 protection to help prevent sunburn and future skin issues.

You can lock the zipper into place to keep it where you want. However, it’s not subdued and can chafe. This tri suit has a pad that is helpful rather than hindering. It actually helps keep you cool. It won’t retain water or drag during a swim.

This tri suit dries very quickly. It has a compression fit and will retain its shape well even after being used in chlorinated pools.

Another benefit of this tri suit is that it is UV resistant, which will help prevent sunburns.

As with most tri suits, it fits tightly, but less so than some. Size up if you have doubts. Some men might feel exposed because the crotch area offers less support than many expect from a tri suit. Some users wear spandex or bike shorts to help with this issue.

The Performance tri suit has padding comparable to what you find on bike shorts. It drains very quickly and does not drag when swimming or running.

There aren’t any color options for this tri suit. It has a sleek black design with light blue piping for a subdued look.

Our Criteria for 10 Best Tri Suits for Triathletes

Performance, durability, and cost comfort are the most important points which we reviewed.

When comparing the different tri suits we looked very closely at  fabrics, we wanted to know what beneficial properties were engineered into the fabrics for the purpose of enabling or even enhancing your personal performance?

We looked at Form Fit, to ascertain that though you get a snug fit, do you still get the needed flexibility for your body, especially while swimming, cycling and running?

Do the tri suit designs factor in the different conditions under which the suit performs for swimming, running and cycling? Running postures are very different from swimming and cycling, does the suit allow for this?

Moisture wicking and the ability to dispel large quantities of liquid were a very important factor, having swam in a suit, can you be comfortable knowing that it will rapidly dry out while you cycle and not hinder your performance?

Featuring very high was the aerodynamic performance of the suit, we found that designers had been ingenious, incorporating innovative thinking into the construction of suits to increase the aerodynamic qualities and give the contestants more speed, vital extra seconds which would clock up over long distances.

Carrying nutrition was very important, the triathlon events are grueling and the need to conveniently carry nutritious energy giving food is a must.

For comfort and protection we even looked at anti chaffing qualities built into the suit, protection from the sun and protection from friction.

We wanted to know how light and durable the suits are? When fitted with zip systems were the zip systems durable? We found as with all zip systems, they work great but the user must not over exert pressure when zipping as damage can occur, especially during a frantic fast transition moment.

Cost was a factor and we found the cost theme remains constant, the more you pay the better you get.


Something Else To Think About

So there you have it, our top five best tri suits for triathletes. Above all else our advice would be to not settle until you’ve found one that fits perfectly, and we really do mean perfectly. The last thing you want is to hamstring yourself (in an already difficult task) with gear that doesn’t quite do it for you. For a little bit more information on Tri Suits versus Wetsuits read on.

Tri Suits versus Wetsuits

Image result for tri suitVersus Logo. VS Vector Letters Illustration. Competition Icon. Fight Symbol.Confident man with short hair wearing wetsuit. Kite surfer.

To some extent whether or not you go for a tri suit or a wet suit will be down to the the rules and regulations of the particular race you are competing in. But beyond that personal preference comes into play quite a bit.



Tri Suits: If you can get away with using one by all means go for it. The simplicity of not changing at all throughout the course of the race is a huge bonus. Then again in some situations you absolutely need a wetsuit and the benefit they entail. So just make sure know the conditions and rules well before and plan accordingly.

Wet Suits: A wetsuit is generally made from neoprene material,  is buoyant, and helps keep you warm. A tri suit is not buoyant at all. Wetsuits also come in different styles and variations, you want to get one that is geared for triathletes specially if possible.

If the triathlon you are participating in is in open water and that water is predicted to be at all cold, a wet suit is going to help. Wetsuits are also very beneficial to weaker swimmers. So if you’re just starting out or swimming isn’t your strongest point, there can be a real advantage to the wetsuit. Often times triathletes (by the nature of their training) don’t have tons of body fat, this can mean you get colder in the water faster than average so the wetsuit can provide additional benefit there.

The bottom line is know your conditions, know your body, understand the rules and from that point deciding whether to go for a tri suit or full wetsuit is relatively easy.



Q: Which are better, wet suits or tri suits?

A: Wet suits tend to be heavier on fabric in their design and, in turn, are heavier in general. Wet suits also have a tendency to accumulate more water, again adding to the wears overall weight. If the triathlon is taking place in open water or exceptionally cold water then a wet suit may be preferable, otherwise we recommend a tri suit.

Q: What can I do to prevent chaffing?

A: Doing research and reading through reviews will give you a good idea of what gear is best to prevent chaffing. You’ll want to find a tri suit that has proper materials and design to minimize the chaffing you will experience.

Q: Is it possible to develop a skin infection while running a triathlon?

A: The combination of fresh or salt water, sweat, and the heat of friction is the perfect environment for breeding bacteria. A tri suit designed with antibacterial materials as well as sufficient wicking properties would be able to minimize the chances of developing an infection.

Q:Is there a suit I can choose that would help reduce my run time?

A: Choosing a suit that will eliminate wind and water drag is essential to this, but it is also important to consider how easily the suit transitions to different activities.

Q: Wouldn’t a full body tri suit add to my run time if I need to use the bathroom?

A: Tri suits designers are now quite aware of the problem and have started making their suits with removable panels so that the gear that was made to help you won’t be slowing you down.
