Your Next-Level Fabric: Built for Champions


Because Ordinary Fabrics Can’t Keep Up with Your Drive

  • Indestructible Foundation: 85% Nylon backbone resists abrasion, 15% Spandex ensures 4-way stretch for unrestricted movement.

  • Unrivaled Longevity: Outlasts standard activewear fabrics by 300% in wash tests (independent lab data), maintaining shape through intense use.

  • Uncompromised Performance: Never sacrifice comfort for performance—stay supported during marathons, yoga, or daily grind.




SiTEX™ Technology: The Science Behind Your Success

Revolutionary Feature

How It Transforms Your Life

95% FIR Reflectivity (US/TW Patented)

Converts body heat into 4-16μm far-infrared waves, boosting blood flow by 15%*—accelerating muscle recovery and reducing fatigue

Permanent Mineral Embedding

Unlike temporary-coated fabrics, SiTEX™ maintains full functionality after 50+ washes, ensuring lifelong wellness support

Intelligent Thermal Regulation

Automatically adapts to your body’s needs—trapping warmth in the cold and enhancing breathability in the heat




Designed for Every Moment, Crafted for Every Lifestyle


Where Innovation Meets Infinite Possibilities

  • Athletic Pursuits: Compression-fit design reduces muscle fatigue, making it the perfect choice for high-intensity training gear, from running shorts to cycling jerseys.

  • Urban Adventures: Its sleek texture resists wrinkles, ensuring you look sharp from the gym to the city streets.

  • Wellness Journeys: The gentle embrace of far-infrared waves supports joint flexibility, making it ideal for recovery wear and relaxation apparel.
