Designed by pilots for pilots! The soft silicone nose piece, streamlined temple tips and light weight will make you forget you’re wearing them. In addition to the enhanced fit and comfort, the streamlined ear pieces make sliding your Blockalls on and off while wearing your headset effortless. Blockalls have a soft opaque finish that blocks out distracting sunlight and are the only IFR view limiting device designed exclusively with an off centered patent pending clear viewing area that helps the pilot’s eyes stay focused only on the instrument panel with minimal outside distraction. Blockalls are specifically made for the left seat pilot in command. Made in the USA of domestic and imported materials.
