The Yonex Mavis-350 badminton nylon shuttle is probably the best-selling nylon shuttle in the world. Yonex Mavis nylon shuttlecocks are precision products and possess nearly the same flight characteristics as a natural feather shuttlecock. The combination of excellent spinning properties and the extremely long durability of Yonex Mavis nylon shuttlecocks makes even long rallies a true pleasure. In smash tests reaching speeds of up to 300 km/h, Yonex Mavis nylon shuttles stabilized after just 0.020 seconds, only 0.005 seconds longer than a natural feather shuttlecock. This means that the Yonex Mavis takes only slightly longer to achieve a stable flight path.
