Reduces SI joint pain: If you spend long periods of time sitting, your lower back may start to feel stiff and sore. The BackWonder sacroiliac belt can help by providing support for the lower back and SI joint, reducing pain and enabling you to sit for more extended periods of time with less discomfort.

The wide, soft neoprene foundation strap includes a moisture-absorbent lining. “Non-slip” panels hold the pelvic support in place while allowing you to move around without restriction. Easy to use: Wear this sacroiliac belt for women or men over your “underwear”. Position the Back-Wonder SI joint belt with the blue center-line stitching of the “cinch straps” centered just above your buttocks. The buckle will then be offset to one side. Position it LOW so that the SI belt is BELOW your hip bones. Once positioned, thread the end of the SI belt through the metal buckle and pull snugly to lock it in place with “hook and loop” material. Reach back grab the “cinch strap” on each side by the webbing at its’ end and pull firmly. Again, securing with “hook and loop” material.
