Offering an ideal blend of power and control for the intermediate through advanced player, the Biomimetic 400 is an appealing choice for a variety of playing styles. With a more solid feel than the 500 range, this one still feels easy to maneuver. Easy acceleration through the hitting zone makes both pace and spin effortless to develop. The level of comfort from all areas of the court impressed our TW playtesters. At net the racquet feels crisp and precise. Targeting is spot on both when punching volleys deep as well as when caressing the ball with touch. As from the baseline, power and spin is also easily generated on serve. Perfectly filling the gap between the control oriented 300s and light, more powerful 500s, this 400 blends elements of both and impresses greatly.

This technology is inspired by shark skin. The unique surface appplication is strategically applied to the racquet frame. The dimpled texture creates localized turbulence and streamlines airflow over the racquet surface. This reduces drag by up to 25%, resulting in a faster racquet speed for more power.

HM6 Carbon

This technology is inspired by a bee's honeycomb. High modulus carbon fiber is engineered into hexagonal sheets and is placed between layers of Aerogel-enhanced carbon. These hexagonal sheets help evenly distribute impact forces and absorb unwanted racquet frequencies to enhance feel up to 10%. The HM6 Carbon reduces energy loss and maximizes energy return.

Gecko-Tac Grip

This unique nano-scopic surface treatment on the grip is inspired by gecko setae. The perforated design increases moisture reduction and provides up to 50% more grip and tack. This results in enhanced control, precision and comfort.

CX Technology

CX Technology is inspired by the wings of birds of prey to reduce aerodynamic drag in the hoop. This combined with a TruOval head shape greatly increases the racquet's sweet spot to maximize power. CX Technology = enhanced racquet speed and power.


Inspired by the sandfish skink, a lizard that can swim through sand, Dunlop's unique grommet technology combines microscopic ridges with a near frictionless, high strength polymer that provides greater string movement and improved aerodynamics for added penetrative power. AFG = Enhanced power.

Anatomic Construction

Apex predators are highly evolved for power and precision. Taking inspiration from their anatmoical bone structure, Dunlop has inverted the structural form of the throat in 3 key areas to minimize torsional deflection for increased precision and control on off-center shots. Anatomic Construction = Enhanced control and precision.
