The combination of close-to-feather shuttlecock flight performance and four to five times more durability than an ordinary nylon shuttlecock makes the YONEX MAVIS series the most cost-effective choice for practice sessions. The Mavis 2000 is designed to be the ultimate practice and tournament shuttlecock for club players. The hardness of the skirt – the feather part of the nylon shuttlecock – varies depending on temperature.
