Nite Ize is an all-American company started through true entrepreneurial spirit in 1989, by a fisherman frustrated with his options for fishing at night with a flashlight, so he sought to build a better mousetrap. Today they make a host of nifty remora-like accessories for flashlights, as well as other offerings, and are the embodiment of the American small business success story.
The Nite Ize Headband was designed hand in hand with the enormously popular Maglite brand but very likely works with most little flashlights. Two loops on the side affix by that ubiquitous hook-and-loop tape to secure your flashlight and elevate its status to supreme headlight. You'll likely notice that while in use the beam of light will follow wherever you gaze; this is normal and to be expected.
