With its sleek, attractive View Limiting Device, ViBAN® brings pilots a new level of comfort and functionality during simulated IFR operations. Weighing just 1 oz., you'll hardly notice you're wearing anything at all. Its black color effectively prevents sunlight glare that can plague white or frosted devices, and its revolutionary construction is tough and won't scratch like safety glass lenses do. The earpieces allow for easy headset use, and the device can even be worn over eyeglasses - simply remove the nose piece first. Purchase includes both a hard case and a cord for easy storage and portability. A phenomenal item for stylish, trouble-free simulated instrument flight. Unlike traditional view limiting devices, you'll never have to worry about a Viban fogging up in the cockpit while wearing PPE.
