Core Performance Highlights
48g Ultra-Lightweight: At just 48 grams (Men's Size L), this singlet minimizes weight interference, allowing you to focus entirely on your pace.
3D Bionic Dragonfly Mesh: Featuring Toray Dynamic-Stretch fabric, the unique texture mimics dragonfly wings to create a high-speed ventilation micro-climate around your body.
One-Way Moisture Wicking: Advanced moisture-management technology rapidly expels sweat to the outer layer, preventing the fabric from sticking to your skin and reducing the risk of chills post-race.
Seamless Comfort: Utilizes Ultrasonic Bonding and Flatlock Stitching. No tags, no rough seams—eliminating chafing in sensitive areas like the underarms and chest during long-distance runs.
2026 Special Edition: "Orange Sprint"
Celebrate the Year of the Horse with our high-saturation "Orange & Black" collision design. Featuring ink-wash horse patterns, this kit ensures you stand out in the marathon crowd for both speed and style.
