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.When smashed, a MAVIS shuttlecock recovers in only 0.02 seconds. This performance is just 0.005 seconds slower than a YONEX Feather shuttlecock and 0.008 seconds faster than the recovery of an ordinary shuttlecock.
