With its unique design, the Med Spec® SI Belt helps stabilize and support the sacroiliac joints. The inner elastic belt with plush lining may be worn directly next to the skin and underneath clothing. Strategically placed SkinLoc™ pads grip the skin or underlying clothing to prevent the belt from migrating. The outer nylon belt provides the circumferential pressure necessary to stabilize the sacroiliac joints. The low profile posterior plastic panel and foam pad provide additional compression to the sacrum and help immobilize the sacroiliac joints.
