The Head Boom MP 2022 Tennis Racquet is manufactured in China and has a graphite composition. The racquet’s head size is 98 square inches and length of 27 inches. Key Features: AUXETIC : Auxetic constructions show a unique deformation compared to non-Auxetic constructions. Due to their internal properties, Auxetic constructions widen when a “pull” force is applied and contract when squeezed. The bigger the applied force, the bigger the Auxetic reaction. UNI PATTERN : The specially designed uniform string pattern allows for a consistent ball trajectory on every shot for reliable and forgiving play. DIRECTIONAL DRILLING : Directional drilling combine increased power and sweetspot, delivering a plush impact feel. GRAPHENE INSIDE : Strategically positioned in most of our racquets, Graphene strengthens the frame, provides greater stability and optimises energy transfer from racquet to ball. When you buy your next racquet, be sure it has GRAPHENE INSIDE. MORPH BEAM : The unique frame construction merges an elongated box beam shaft with a powerful head for the perfect blend of feel and ease on court. POWER GROMMETS : The enlarged power grommets maximize string movement for increased power.
