The Protective Rain Cover/wetSuit for the ARRI Alexa Camcorder with MB17 or 18 Matte Box from camRADE is manufactured from flexible, waterproof polyvinyl chloride that surrounds your camcorder protecting it from dust, sand, water, and other elements. When the cover is deployed, you still maintain total access to your controls and LCD screen, REC button, SSD slot and all camera in/outputs. The interior is made from a cotton material designed to minimize noise from wind and rain. Vinyl windows provide complete view of the camcorder's controls. The wetsuit is secured with elastic and zippers. It comes packed in a zippered pocket for easy transport.
