Tri Suits

Tri suits, short for triathlon suits, are specialized performance garments designed specifically for triathletes to wear throughout all three stages of a triathlon event: swimming, cycling, and running. These innovative one-piece or two-piece suits provide triathletes with optimal comfort, support, and functionality, enabling them to transition seamlessly between disciplines without the need to change outfits.


A tri suit is a versatile, all-in-one garment engineered to meet the unique demands of a triathlon. It combines the features of a swimsuit, cycling shorts, and running apparel into a single, streamlined package. Tri suits come in two main styles:

  • One-Piece Tri Suits: These suits offer a sleek, aerodynamic design with fewer seams, minimizing drag and maximizing performance. They typically feature a front or back zipper for easy wearing and removal.
  • Two-Piece Tri Suits: Consisting of a separate top and bottom, two-piece tri suits provide greater flexibility and comfort, making them easier to manage during transitions or bathroom breaks.
Sizing and Fit:

Tri suits are available in a wide range of sizes, from Extra Small (XS) to Extra Extra Large (XXL), to accommodate various body shapes and preferences. When selecting a tri suit, aim for a snug, form-fitting design that contours to your body without restricting movement or causing discomfort. The suit should allow for a full range of motion across all three disciplines while minimizing wrinkles or flapping fabric that could increase drag.

Materials and Construction:

High-performance tri suits are crafted from advanced technical fabrics that prioritize comfort, durability, and functionality. Common materials include:

  • Lycra/Spandex: Known for its excellent stretch and recovery properties, Lycra or Spandex ensures a close, supportive fit that moves with the athlete.
  • Nylon: Durable and quick-drying, nylon fabric is often used in tri suits to enhance longevity and moisture management.
  • Polyester: Prized for its moisture-wicking capabilities and breathability, polyester helps keep athletes dry and comfortable during intense exertion.

Many tri suits also incorporate additional features, such as UV protection to shield the skin from harmful rays and chlorine resistance to extend the suit's lifespan when used in pools.

Benefits and Unique Features:

The thoughtful design and construction of tri suits offer numerous benefits to triathletes:

  • Hydrodynamic and Aerodynamic Efficiency: The smooth, form-fitting surface of a tri suit reduces drag in the water and wind, optimizing performance during the swim and bike segments.
  • Comfort and Support: Integrated chamois padding provides cushioning and support for the cycling leg without adding bulk or hindering movement during the run. Flatlock seams minimize chafing and irritation, ensuring all-day comfort.
  • Moisture Management: Quick-drying, moisture-wicking fabrics pull sweat away from the skin, regulating body temperature and preventing discomfort across all three disciplines.
  • Practical Features: Strategically placed pockets allow athletes to carry essential nutrition and gear without compromising aerodynamics, while zipper closures enable customizable ventilation.
  • Compression and Muscle Support: Many tri suits offer gentle compression to support working muscles, reduce fatigue, and promote efficient blood circulation.
Protection and Versatility:

In addition to enhancing performance, tri suits offer critical protection for triathletes:

  • UV Protection: Built-in UV barriers shield the skin from harmful ultraviolet rays, reducing the risk of sunburn and long-term skin damage.
  • Chafing and Irritation Prevention: The smooth, seamless construction of tri suits minimizes friction against the skin, preventing painful chafing and irritation during extended periods of exertion.
  • Quick-Drying Properties: The suit's ability to dry rapidly after the swim segment helps maintain body temperature and prevents the discomfort and chilling effects of remaining wet during the bike and run.

Beyond their protective qualities, tri suits are incredibly versatile, eliminating the need for separate garments for each leg of the race. This not only streamlines transitions but also allows athletes to focus on their performance rather than wardrobe changes.

Choosing the Right Tri Suit:

When selecting a tri suit, consider factors such as the distance and conditions of your target events, your individual body type and preferences, and the suit's overall quality and construction. Look for suits with flatlock seams, moisture-wicking fabrics, and a chamois that provides ample support without feeling bulky or restrictive.

Additionally, consider the suit's unique features, such as the type and placement of pockets, the effectiveness of any compression panels, and the suit's overall aerodynamic properties. Trying on multiple styles and brands can help you find the perfect tri suit that balances comfort, performance, and personal preferences.


Cycling tri suits are a game-changing piece of performance apparel for triathletes of all levels. By combining the best features of swimwear, cycling gear, and running attire into a single, streamlined garment, tri suits enable athletes to focus on their race, transition seamlessly between disciplines, and unlock their full potential. With the right tri suit in your arsenal, you'll be equipped to tackle any triathlon with confidence, comfort, and unbeatable performance.
