The RAINMAN is made of a soft, lightweight batting that does not absorb water or mat up when wet. Instead, the rain drops simply slow down as they flow through and are channeled out the front. The exterior is net material with sturdy stitching and a Velcro closure. The RAINMAN easily slides onto most windscreens, and is secured with Velcro.

The RAINMAN goes on and off quickly and easily. To install the RAINMAN, simply slide it on with the open end at the front of the microphone then close the Velcro slot.

In heavier rain, the RAINMAN may eventually take on water faster than it can channel it through. In this case, it may be a good idea to occasionally remove the RAINMAN and shake or wring the water out. With a little experience you will get a feel for when and how often this should be done. The RAINMAN's effectiveness has been proven in actual production environments.

It is recommended that the RAINMAN be used without a furry wind cover. However, for added wind protection, a stretchy "sock" over may be used under the RAINMAN.
