2G-Namd Flex Force
2G-Namd Flex Force is a highly elastic graphite material that allows the frame to flex and snap back quickly during impact. It is designed to support ball pocketing and spin potential while retaining a responsive feel.
The Yonex PERCEPT 100D in Midnight Navy is for players who attack decisively but prefer the ball to leave the strings in a measured, predictable way. At a nominal 305 g, it brings a little more mass than the standard PERCEPT 100. The more significant distinction, however, is its 18/19 string pattern. That denser arrangement is attractive to confident ball strikers who value directional accuracy and trajectory management during quick, physical rallies.
Denser strings, clearer intentions
PERCEPT 100D keeps the useful 100-square-inch head rather than demanding the precision of a 97, yet it feels conceptually closer to a focused control frame than to an easy-power racquet. The ISOMETRIC shape offers some forgiveness, while the tighter pattern asks for a committed swing and an active player who can create pace independently. It is not necessarily the best option for someone still developing consistent contact.
FlexCon System, 2G-Namd Flex Force and SERVO FILTER explain the connected, slightly pocketing response Yonex seeks in PERCEPT. A reinforced racquet face complements that design with an emphasis on stable ball direction. Midnight Navy changes the visual character, not the established construction, making this a sophisticated alternative for players who already know why they prefer a denser string bed.
Technologies
FlexCon System
The shaped, elongated shaft is engineered for controlled flex through contact, extending the ball-pocketing sensation and supporting deliberate placement on well-executed strokes.
ISOMETRIC
Yonex ISOMETRIC uses a more squared-off head geometry that optimizes main and cross string intersections. Yonex reports an approximately 7% larger sweet spot than a comparable conventional round head, supporting a more forgiving response when contact is off centre.
Servo Filter
SERVO FILTER is an elastic film integrated between graphite layers in the frame. It is designed to reduce unwanted vibrations while preserving useful feedback to the hand for a more precise impact feel.
Stiff Racquet Face Design
Additional graphite layers reinforce the racquet face during impact. Yonex positions this as a way to stabilize ball trajectory and improve shot-to-shot consistency while allowing the shaft to retain its designed flex.
