To ensure a proper fit, Rycote has included an internal foam insert. The internal foam is designed to hold many popular-sized lavaliers and also to provide the air space required to make the WindJammer effective. In some instances, you may prefer to use the foam or metal windscreen that came with your lavalier. Simply remove the supplied foam and insert the microphone with the original factory windscreen into the WindJammer.

The Furry uses short WindJammer material with an elastic bottom. A Rycote label on the opening provides a quick and easy method for inserting or removing the microphone. In use, the label may be turned behind or tucked into the Furry to allow the synthetic fur to better blend into the surrounding clothing.
