The Yonex Twin Wave Grap (AC139EX) in Black is an advanced contoured overgrip featuring a dual-layer rubber strip running through its core under a tacky, perforated polyurethane outer layer. When wrapped around the handle, it creates a raised spiral wave ridge that significantly enhances finger lock, structural traction, and impact absorption.
Performance Profile
- Contour & Mechanical Hold: 10/10 — The twin rubber center strip forms pronounced raised ridges that give your fingers natural grooves to lock into, dramatically reducing grip slippage without forcing a tight squeeze.
- Absorbency & Moisture Dispersion: 9/10 — Surface perforations work alongside the recessed channels between wave ridges to direct perspiration away from primary contact zones.
- Tackiness & Security: 9/10 — Combines Yonex’s high-tack PU surface coating with deep structural texture for supreme handle control on hard smashes and off-center hits.
- Durability & Aesthetics: 8.5/10 — Built with high-density polyurethane that withstands heavy friction, with a sleek black colorway that effectively conceals dirt, sweat stains, and oils over time.
- Cushioning & Shock Absorption: 8.5/10 — Varies from 0.65 mm in the flat base up to 2.6 mm at the peak of the wave ridge, dampening harsh frame vibration on high-impact shots.
Best Suited For
- Players Wanting Ergonomic Finger Grooves: Excellent for athletes who struggle with flat overgrips twisting during rapid racquet rotation or finger-tip adjustments.
- Heavy Sweaters: The combination of perforated surface holes and ridge channels prevents sweat accumulation from breaking hand traction.
- Stealth & Classic Styling: Ideal for players looking for a clean, understated aesthetic that pairs seamlessly with any racquet frame color.
- Multi-Racquet Use: Cut to length for badminton handles, but versatile enough to wrap tennis, squash, or pickleball grips.
