NEXTFernand Petzl, an avid caver, set a depth record for cave descents in 1952, the same year Sir Edmund Hilary summited Everest. In his quest to help cavers be faster, lighter, and more efficient, Petzl put a headstrap on a light and took the battery pack off the waistbelt, mounting it on the headstrap as well. He made his first prototype from elastic cut from his wife’s bra.
Petzl headlamps were originally a light source for cavers
