Triathlon Wetsuits Q&A

Question: What is a Triathlon Wetsuit?

Answer: A triathlon wetsuit serves a number of functions.  It maintains body heat while swimming.  Improves buoyancy in the water.  It reduces friction between skin and the body of water.  And finally it is designed to be easy to remove in the transition before heading out on the bike.  

Question: Do you need a Triathlon Wetsuit to Race in a Triathlon?

Answer: If you are entering a pool based swim then the simple answer is No.  If it is in open water then the answer is slightly more complex and depends on conditions.  If water temperature is below 25 degrees you will likely need a triathlon wetsuit.  Exact temperatures vary depending on local region rules.  

Question: What is the Best Triathlon Wetsuit?

Answer: The answer to the best triathlon wetsuit will depend on the individual buying the wetsuit.  We have created the following guide to help you find the best triathlon wetsuit for you.  Key factors to consider are price, buoyancy and flexibility.  

Question: How thick should a Triathlon Wetsuit be?

Answer: The thickness of a triathlon wetsuit varies around the body depending on the level of flexibility and buoyancy needed.  In general you are looking for thinner neoprene around the shoulders for flexibility.  Around the middle section and upper legs you will be looking for thicker neoprene for increased lift and buoyancy.

Design of the Orca 3.8 Orca 3.8 triathlon wetsuit review

Having been a fan of Orca triathlon wetsuits for over a decade the Orca 3.8 continues to cement this loyalty. It is an extremely comfortable wetsuit and gives a high degree of buoyancy around the core. If you are looking for a wetsuit to help you swim with a more horizontal swim position then this is a great choice. The buoyancy across the core, bum and upper thighs is fantastic. Is it the fastest wetsuit on the market? I’m not totally convinced as I feel there are quicker wetsuits but maybe that is just me getting slower! The Orca 3.8 is an incredibly comfortable highly technical wetsuit and perfect for anyone after loads of buoyancy.

Pros and Cons of the Orca 3.8

Pros – Good level of buoyancy from core suiting “lazy legs” swimmers

Cons – Restricts natural roll of swimming more than other wetsuits

Zone3-Vanquish-Wetsuit-Review

The most expensive wetsuit in our line-up of 15 of the Best Triathlon Wetsuits for 2021 and a firm favourite in the Trivelo offices. The Zone3 Vanquish wetsuit is highly recommended for any swimmer that does not naturally need much help with buoyancy. From our expert review Jason, he commented that he was not a fantastic swimmer by any means. Usually swimming around 30-32 mins for 1900m (70.3 swim). 61-64 mins for the full distance Ironman/Long course 3800m swim. The Zone3 Vanquish wetsuit allowed him to swim at his best without having to worry whether or not I am actually swimming well.
