Adidas Estro .40 Hockey Stick (2026 - 2027)

The Adidas Estro .40 (often labeled as the Estro .4) is an entry-to-mid tier composite field hockey stick built for intermediate club players and developing athletes. It shares the exact same physical profile and technical specifications as the women's Ina .40 but features standard unisex branding.

The .40 designation indicates a 40% carbon composition (a 40 Power Rating), with the remaining 60% of the stick composed of flexible fiberglass and aramid. This fiberglass-dominant construction yields a highly cushioned, forgiving touch that simplifies ball control and clean trapping, making it an excellent choice for players transitioning to more advanced skill sets.

Key Features

• Mid-Low Bow Profile: Features a balanced 24mm curve positioned 250mm from the head. This traditional profile provides a clean, flat surface area optimized for flat hard hits, sweeps, and precise push passing, while still allowing for controlled lifting and basic 3D skills.

• Pure Control Head Shape: A distinct, aerodynamic hook profile designed to optimize the hitting surface area while shedding excess weight. It helps stabilize the ball during quick, multi-directional stickwork and tight traps.

• 3D Geometry Shaft: The shaft utilizes a specialized trapezoidal shape with a cut-away underside. This structural spine stiffens the stick to limit twisting under heavy loads, ensuring cleaner and more accurate slap-hits.

• Fiberglass-Dominant Matrix: Because fiberglass makes up the majority of the composite blend, the stick offers excellent shock absorption. This drastically reduces harsh hand-sting on cold days or off-center strikes.

• Internal Compression Core: Built into the head shape, a specialized core expands during manufacturing to tightly pack the composite layers. This eliminates internal air pockets, broadens the hitting sweet spot, and absorbs harsh vibrations on impact.

• ACT Edge Protection: Reinforced along the backhand edge with high-impact nylon materials. This shields the stick from premature wear caused by turf friction and dampens harsh vibrations on reverse-stick (tommy) shots.
