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.\n\nWhen 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.\n\nPlayers should always use the shuttlecocks best suited to the playing environment. The hardness of the skirt – the feather part of the nylon shuttlecock – varies depending on temperature. In the cold, as the skirt becomes hard, it is prone to breaking. In the hot, the skirt becomes softer and less likely to break, but the feel at impact is affected by the softer skirt.\n\nYONEX manages product quality by categorising MAVIs into 3 temperatures. Please ensure that you choose the shuttlecock best suited to the playing environment.\n\nDeveloped using the flight timing of feather shuttlecocks, MAVIS Nylon shuttlecocks are precision designed and manufactured to provide accurate flight performance.
