The RYCOTE RISTRETTO LAVALIER WINDJAMMER : PACK OF 2 is a pair of discreet foam wind covers for use with lavalier mic foams. Using a wind cover can help to protect against the detrimental effects of wind noise on captured audio. This cover is similar to Rycote's Lavalier Windjammer but has shorter fur for a more discreet presence. It is secured to the microphone with a foam connector and has a rubber ring for better grip and retention.
