The YONEX technology and the extensive know-how in production make the big difference for perfect flight stability.
The exact observation of production parameters in a production environment with constantly controlled temperature and humidity guarantees that every YONEX shuttlecock is optimally suited for the required maximum performance. The use of the finest Portuguese cork and the strict selection of only 7 goose feathers for each wing is the basis of the unique quality standard of the AEROSENSA® natural feather balls.
The AS 40 is a top championship and tournament shuttle.
