What clothing do you need to compete in a triathlon? Guide by type of event and distance

The professional triathlete and Inverse ambassador Sara Perez Sala shares her experience on how to choose the ideal custom triathlon apparel depending on the type of event and race conditions.
Choosing the right triathlon wear is one of the most important factors in improving your performance in competition. Whether you’re preparing for your first sprint or taking on an Ironman challenge, your outfit can make all the difference.
In this guide, we explain the differences between the ranges that Inverse offers, and which features you should prioritise when customising your outfit.

Why is it so important to choose the right triathlon wear?
Triathlon is a combination of swimming, cycling and running. This means that the clothes you wear must be suitable for all those disciplines, provide maximum comfort, freedom of movement and reduce friction and transition times.
In addition, the right choice of fabric, fit and design can help you maintain optimal body temperature, protect you from the sun, and prevent chafing, especially in long-distance events.

What range of custom apparel do I need for each type of triathlon?
Inverse offers three major ranges of custom triathlon apparel, specifically designed to suit different types of competitions: short, medium and long distance, and events with or without neoprene.

TERRAM range – Ideal for duathlons and triathlons with wetsuits
This range is designed for events where neoprene is mandatory or recommended. The fabric in the TERRAM range is optimised in order to maintain comfort after leaving the water, and provides excellent muscle support while cycling and running.
Who is it for?
Triathletes competing in duathlons or middle or long distance triathlons, when using neoprene means that the hydrodynamics of the suit is not as important.
Key features
- Ergonomic suits, tops and pants
- High levels of breathability
- Flat seams to avoid chafing
- Full customisation, with club or sponsor’s colours and logos

AQUA range – Designed for events without neoprene and short distances
Your wetsuit’s fabric becomes a key factor in warmer water and when neoprene is not allowed. AQUA is a hydrophobic range, which repels water, improves streamlining while swimming, and dries quickly during the transition.
Who is it for?
Ideal for triathletes competing in sprint or Olympic triathlons, when every second counts.
Key features
- Second skin effect fabric
- Ultra fast drying
- High elasticity for a perfect fit
- Water repellent while retaining breathability

AERIS range – For long distance and maximum aerodynamics
In events such like the half Ironman or the full Ironman, staying comfortable for hours is as important as aerodynamics. The AERIS range has been developed with professional triathletes to optimise performance in extreme events.
Who is it for?
Triathletes competing in long distance triathlons looking for high performance, comfort and storage (for nutrition, accessories, etc).
Main advantages
- Aerodynamic design
- Integrated pockets without air resistance
- UPF sun protection
- High-performance fabrics tested in competition

Sara Perez Sala’s tips for choosing your custom triathlon apparel
In one of her recent Instagram reels, the professional triathlete Sara Párez Sala explains how each competition requires a strategy… and the right outfit. According to Sara, the suit looking nice and being the same colour as the team’s is not enough – it must also be functional:
- “The fit has to be perfect to avoid wrinkles that slow you down.”
- “Pockets are essential over long distances for carrying gels or bars.”
- “You really notice some fabrics in the water. If you can compete without a wetsuit, that can give you extra seconds that may be important.”
Sara has also provided numerous comments on our triathlon suit ranges in her capacity as a professional triathlete, applying her sporting expertise to the design of triathlon apparel that combines style, functionality and performance.

How to choose the best custom triathlon apparel?
Before choosing your racing suit or outfit, ask yourself:
- Am I going to compete with or without neoprene?
- What distance am I going to run?
- What weather conditions will I come across?
With this information, you can decide between Inverse’s TERRAM, AQUA or AERIS range, and customise your garments with your name, logo or club colours.
Remember: a good triathlon outfit is not only comfortable – it can also make the difference between a good result… or a spectacular one.
