The Remote Audio REM MCATG Micro Cat Miniature Windscreen allows the use of lavaliere microphones in windy conditions that would otherwise cause serious audio problems. They really work.
Hand-made from a fuzzy outer layer plus two additional inner layers of open weave fabric, the Micro Cat very effectively stops wind from reaching the microphone to substantially reduce wind noise while remaining sonically transparent. The elastic opening easily fits over most lav microphones with diameters of up to 12mm.
Narrow microphones like the Sanken COS-11 fit securely in the Micro Cat with their mesh windscreen installed. Even the tiny Countryman B-6 works well in the Micro Cat when combined with the microphone's foam ball.
Because of the increased potential for clothing noise when concealed, the Micro Cat is best used outside clothing, fully exposed. The Micro Cat's neutral gray or black colors can often go completely unnoticed in long, wide shots.
