The Mavis 350 shuttlecocks come with more resistance and durability. These shuttlecocks come with a green cap and are mostly made up of nylon, making them tougher and more ideal for practice sessions. These shuttlecocks are precision designed and manufactured to provide accurate flight performance. And unlike most Yonex shuttlecocks, these shuttlecocks are available in yellow colours instead of white. 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, these shuttlecocks recover only in 0.02 seconds, which is 0.08 seconds faster than the recovery of an ordinary shuttlecocks.
