Lumbar Back Support Belt: This sacroiliac belt for men and women helps provide relief for back pain, spasms and referred pain in the hip, pelvis, or sciatic pain. Comfortable Lower Back Pain Support: The SI-LOC acts as a sacroiliac brace and sciatica pain relief belt by stabilizing the SI joints and pubic symphysis.

Professional Designed Lumbar Support Belt for Women and Men: Designed by a Doctor of Physical Therapy, the SI-LOC’s unique shape (wider at the sides), ensures that pressure is more evenly dispersed. This helps hold the ilia tightly against the sacrum, stabilizing the pelvic ring. Large/Extra-Large Fit Measurements: Size large/extra-large fits pelvic circumference 47”-60". To fit, measure the pelvic circumference at a level one inch above the most superior aspect of the greater trochanters. Made in the USA. FSA or HSA eligible. Therapists prefer the SI-LOC over other back braces, trochanteric belt and sciatic belt, and SI support belts because it stays in place. Patients prefer the comfort of the SI-LOC’s lightweight, breathable fabric and non-bulky design that conceals easily under clothes. 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. As a si joint belt for men, si belt for men, and sacroiliac hip belt for women providing lumbar pain relief, the SI LOC's 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. Serves as a lumbar and back support belt, back wrap and SI joint brace, the SI-LOC is one of the most popular sciatica pain relief products and back supports. Developed by the IAOM-US; patented.
