The 2XU Engineering Philosophy: More Than Just a Suit

At 2XU, our design mandate is absolute: Human Performance. Multiplied. This is not a marketing slogan; it is the scientific principle engineered into every fiber of our apparel. A 2xu tri suit transcends the standard definition of Triathlon equipment; it is a meticulously calibrated performance system designed to optimize every stage of your race. Our entire engineering process is built upon the holistic athletic cycle of Prepare, Perform, Recover. We understand that what supports your muscles during the final 10k of the run is just as critical as what reduces drag in the first 1500 meters of the swim. This unwavering commitment to scientific validation, conducted with world-leading research partners, ensures every garment is a quantifiable advantage, not just an article of clothing.

Compression Science at the Core

The foundation of our performance advantage lies in advanced compression. By engineering graduated pressure profiles, we drastically reduce muscle oscillation-the primary cause of fatigue and micro-trauma. This is powered by our proprietary PWX (Power-Weight-Flex) fabric, a high-gauge elastomeric yarn that delivers an optimal balance of compressive power, lightweight feel, and multi-directional flexibility. The result is scientifically proven:

• Increased blood flow for enhanced endurance.
• Reduced muscle vibration for greater power output.
• Heightened proprioception for improved stability.

Aerodynamics and Hydrodynamics

Victory in triathlon is measured in seconds, where drag is the enemy. Every 2xu tri suit is a weapon against resistance. We utilize wind tunnel testing to validate our aerodynamic fabrics and seam placements, ensuring you slice through the air with maximum efficiency on the bike. In the water, advanced materials like SBR SKIN LITE provide a hydrophobic finish for a faster swim. This is complemented by seamless and bonded construction that creates a smooth, uninterrupted surface, minimizing friction in both water and air for a faster, more efficient race from start to finish.

Perfecting the Fit & Care for Maximum Longevity

The advanced engineering of your 2XU tri suit is only activated by a precise, second-skin fit. An improper fit doesn't just compromise comfort; it negates the scientifically proven benefits of our graduated compression technology. To unlock your full performance potential and protect your investment, meticulous attention to fit and maintenance is not optional-it is essential.

How to Achieve a Second-Skin Fit

A true 'race fit' should feel compressive, holding your key muscle groups firmly to reduce oscillation and fatigue, but it must never be restrictive. You need a complete and uninhibited range of motion for the swim, bike, and run. To achieve this, measure your chest, waist, and hip at their widest points and consult the official 2XU sizing chart. When trying on the suit, ensure there is no sagging or bunching fabric, particularly in the crotch and underarms, as this can lead to significant chafing on race day.

Care and Maintenance Protocol

Your triathlon suit is a piece of high-performance equipment. Treating it as such is critical to preserving the integrity of its advanced fabrics and technical features. Adherence to a strict post-activity protocol will ensure your garment delivers maximum output, race after race. Protect the fabric's engineered elasticity and hydrophobic properties by following these non-negotiable steps:

• Rinse Immediately: After every use, rinse the suit thoroughly in cold, fresh water to remove chlorine, salt, and sweat residue which degrade technical fibers.
• Hand Wash Only: Use a mild, non-detergent soap in cold water. A washing machine’s agitation and harsh detergents will irreversibly damage the fabric's compression profile and bonded seams.
• Air Dry Correctly: Hang your suit to dry inside out, away from direct sunlight. UV exposure and direct heat will break down the elastane, compromising the fit and performance for good. Never use a machine dryer.
