The science behind the grip that's changing racquet sports
What is Hydrocore™?
Hydrocore™ is our proprietary moisture management technology that combines advanced hydrophilic fibers with precision-engineered surface patterns.
Unlike traditional overgrips that simply absorb moisture, Hydrocore™ actively wicks sweat away from your hand, distributes it across the grip surface, and allows it to evaporate through breathable micro-channels. The result is a grip that stays dry, tacky, and consistent throughout your entire match.
2+ Years of R&D
Developed through extensive testing with professional athletes
Lab-Tested Performance
Validated in controlled environments and real-world conditions
Patent-Pending Innovation
Unique material composition and manufacturing process
Instant Moisture Absorption
Advanced hydrophilic fibers pull sweat away from your hand in milliseconds, maintaining a dry grip surface even during the most intense rallies
Temperature Regulation
Breathable micro-channels allow heat to escape while maintaining optimal grip temperature, preventing overheating and discomfort
Adaptive Traction
Precision-engineered surface pattern adjusts to hand pressure and moisture levels, providing consistent grip in all conditions
Extended Durability
Proprietary polymer blend resists breakdown from sweat, UV exposure, and friction, lasting 3x longer than standard overgrips
Four-Layer Engineering
Each layer is precisely engineered to work together, creating a grip system that outperforms in every metric
Surface Layer
Adaptive Traction MatrixMicro-textured surface with variable grip zones that respond to hand pressure and moisture levels
Absorption Layer
Hydrocore™ FibersAdvanced hydrophilic fiber network that wicks moisture away from the surface instantly
