The Rycote Undercover pads are a disposable mount and windshield used for mounting lavalier microphones underneath clothing. There are 3 sheets of 10 fabric discs (30 total) supplied in each package. The pads are made of a soft woven material. The Sticky (adhesive) is peeled onto clothing, providing a tacky mounting surface for lavalier microphones. Place your mic. Then place the woven fabric disc over the microphone and adhesive surface, sandwiching the microphone and eliminating structure and rustling noise caused by the movement of clothing, cables, etc.
