Best Triathlon Suits in 2022

Experienced triathletes know that triathlon suits can improve performance and keep you comfortable during all phases of a triathlon.
Tri suits have skin-tight fabric that promotes muscle compression, which improves performance by increasing blood flow. Mesh panels remove moisture after a swim by improving ventilation and airflow. Most importantly, tri suits can be worn for all phases of the races, offering aerodynamics on the bike and run.
There are two types of tri suits: single-piece or two-piece, a top and shorts. You also have a choice of tank top or short sleeve tri suits.
Single-piece are more popular for races, while two-piece offer more versatility to mix and match. Many are woven without seams to prevent chaffing, and with grip fabric to ensure stability on your bicycle seat.
Our overall pick is the Castelli Sanremo 4.0 Speed Suit, which has dynamic, wrinkle-free fabric that promotes airflow and comfort. But we found many other top picks in a variety of styles and price-points.
Read on to see the rest of our favorites. We’ll help you sort out the best triathlon suits available today.

Why wear a tri suit?

Tri suits are designed to be a single clothing choice for all three legs of a triathlon: swimming, biking, and running. They are ideal for sun protection, moisture-wicking, and form-fitting comfort in all three areas.

When should I wear a single-piece tri suit vs a two-piece tri suit?

Price is a huge factor in deciding which suit to purchase. As far as performance is concerned, single-piece tri suits are ideal for those that plan on practicing all three triathlon disciplines, including swimming. Just the tank top or the shorts can be purchased for less money and may suffice when your focus is running or biking.

How should a tri suit fit?

A tri suit should fit snugly. They’re designed to be form-fitting. However, the skin-tight fabric may make buying a size up necessary, particularly for those who have never worn one. The tightness promotes muscle compression so it becomes necessary for those who want to maximize their performance.

Can I swim in a tri suit?

Tri suits are designed with mesh panels to ventilate your skin and wick moisture. This applies to preventing chafing while running and for drying after a swim. They are ideal for all legs of a triathlon, including swimming.

Do elite triathletes wear a tri suit for the swim?

Elite triathletes wear single-piece tri suits for the entire triathlon. This is for both comfort while biking, as well as for their mesh ventilation panels, which promotes moisture removal after swimming.
