SI-LOC offers relief from low back pain and back spasms, along with referred pain in the hip, pelvis or sciatic pain extending down the leg. Its patented, tapered design is wider at the innominates for even pressure distribution, making it comfortable to wear for long periods while keeping steady, supportive pressure on the SI joint. Wide, medical-grade, non-slip pads prevent the SI-LOC from sliding while dual hook-and-loop closures allow user to adjust the anti-slip buckle to where it is most comfortable.
