Abstract: A belt is formed of a single piece of high strength nylon line approximately 50-100 feet long attached to a belt buckle by a series of longitudinal loops which constitute the warp strands of a woven band. The weft strands of the band are woven through the warp strands in a series of loops, each succeeding weft loop passing through the end of the previous weft loop. At the end of the longitudinal loops, the end of the cord is passed through the penultimate weft loop and is then woven back through the warp to releasably lock the weave. The belt may be rapidly converted to a long single length of survival line by merely pulling the end of the cord out of the warp and through the penultimate loop to unlock the weave which can then be completely unraveled in seconds to yield a long and strong survival line of great utility.
