What Sets the Hexa-Core Apart
Honeycomb Engineering
Most undergrips are just foam. The Hexa-Core uses a 3.0mm high-density silicone honeycomb lattice — the same shock-distribution geometry used in protective sports helmets.
Ergonomic Grip Design
The contoured ridges force the hand into a naturally relaxed position, preventing the death-grip squeeze that strains forearm tendons over long play sessions.

"I've tried elbow braces, ice packs, physio — nothing kept me on the court consistently. The Hexa-Core is the first equipment change that actually made a difference to my game and my recovery."

Try It Risk-FreeCarbon-Fibre Paddles Are Destroying Your Arm
Today's pickleball and padel paddles are engineered for power, not for your tendons. The same stiff carbon construction that delivers a crisp put-away sends a brutal vibration straight up your forearm on every strike.
Over hundreds of swings a week, those micro-impacts inflame the tendons at your elbow — a condition doctors call lateral epicondylitis. You know it as the dull ache that won't go away, the grip that feels weaker, the game you start to dread.
