The VFR Goggle is a smaller version of our original OTE (Over the Eyeglasses) goggle invented by us in the 1970's to satisfy the demands of a growing sky diving population who couldn't enjoy the view while they were jumping. This new design is large enough to fit over most any pair of eyeglasses yet it's small enough to work with helmets including most if not all bicycle helmets. It has small vent holes in the top to prevent fogging.
