The yellow 20015MTLY MicTube Weatherproof Microphone Case from Alfa Case is designed to carry a single shotgun microphone in a padded, waterproof case. The MicTube actually floats if dropped in a body of water (not recommended). Its O-ring-sealed lid keeps out moisture, dust, and grit, and gives your expensive mics good protection.
This MicTube Weatherproof Microphone Case is designed for medium, shotgun microphones up to 15.0" (38.1cm) and comes with a lockable draw-latch top. It mounts to a Boom Tube with a mounting kit (both, sold separately). You can carry additional microphones and a Softi-Case (both, sold separately) on the Boom Tube for a lightweight, over-the-shoulder carrying system that leaves your hands free to have a latté or carry your audio recorder.
