The synergy tri suit is made from a “aquaphobic” nylon-spandex blend that is recognized for its comfort, breathability and compressive qualities.

SLS3 Triathlon

SLS3 Triathlon
The SLS3 tri suit represents a dramatically different price demographic than the ORCA RS1, but differing prices don’t represent as big a dropoff in quality as you might imagine. The tri suit from SLS3 has a number of different things going for it. In no particular order: we found that the padding was excellent for cycling and running and that the super-light nylon/spandex blend from which it is comprised did an good job wicking away sweat. The classic all black design with a few details (blue or lime) gives off a no nonsense vibe. Overall this suit hit all the essential points needed from a tri suit and it does so while maintaining a relatively economical price.

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


To some extent whether or not you go for a tri suit or a we 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.
