The Windjammer first introduced by Rycote is a high quality synthetic fur-cover, which provides the highest possible protection against extreme wind-noise. When using a Windjammer fitted over a Windshield up to 50 dB of wind-noise attenuation can be achieved, producing excellent standard audio recordings.Each Windjammer fits one size of windshield, and comes supplied in every Modular Windshield Kit. Windjammer is also available in sizes to fit Stereo Windshields, Softies & Baby Ballgags, please see their relevant product family for details.The Windjammer is made from materials which are specially designed and manufactured for the purpose, and as a result has virtually no adverse effect on High-Frequency. To be totally effective it is important that the pile of the Windjammer remains in prime condition, so each is supplied with a fold flat hairbrush for ongoing maintenance.

Each Windjammer is designed to fit over it's corresponding Windshield, for example a Windjammer 1 will fit over a Windshield 1 etc.Because the Windjammer is most effective when fitted tightly, their approximate length is 50mm longer than their corresponding Windshield. If you are trying to match a Windjammer to an older or unknown Windshield please check their lengths in the Tech Specs Tab.
