When smashed, a Mavis Shuttlecock recovers in only 0.002 seconds which is about 0.008 seconds faster than that of any other shuttlecock. The combination of close-to-feather shuttlecock 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.Players 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. Shuttlecocks should be stored away from high temperatures and the tube kept upright with the cork side of the shuttlecock facing down.
