The Yonex Aerosensa 40 Feather Shuttlecock White (AS-40) is a premier, elite tournament-grade natural shuttlecock. Sitting as the penultimate model right below the legendary AS-50, it is precision-engineered by Yonex for high-end league matches, national-tier tournaments, and demanding professional play.

• Color : Clean White
• Feather Material100% : Selected Premium Goose Feathers
• Rapid Shape Recovery: When struck at maximum velocity, the aerodynamic cone temporarily compresses to slash air drag, instantly expanding back to its true spinning rotation without wobbling or drifting mid-air
• Crisp Feedback and "Pop": The pure, solid Portuguese cork tip avoids the hollow or dampened feel common in lower-tier composite hybrids. It provides immediate tactile feedback and an exceptional hitting sound ("acoustic pop") upon racket contact.
• Near-Flawless Trajectory: Built as the benchmark for international accuracy, the AS-40 delivers a perfectly smooth trajectory and highly predictable descent. Experienced players can time extreme smashes, tight net drops, and baseline-to-baseline clears with complete directional confidence.
• Extreme Shock Resistance & Durability: Reviews from equipment specialists like CK Yew Badminton and Badminton Bites highlight that the AS-40 matches the AS-50 in durability. The robust goose feather shafts can tolerate immense punishing shocks from modern high-tension rackets before showing any structural wear.
