Flexible Lumbo Sacral Support Belts  are made of a soft material, such as cotton/elastic blends, canvas, and/or neoprene (a type of synthetic, flexible rubber). 
Flexible lumbar belts or corsets typically come in a variety of sizes and designs.  Lumbo sacral support allows some limited bending. It typically include vertical metal or plastic stays at the front, back, and/or sides of the brace that provide stability and some motion restriction.

• Applying light pressure to the torso to help adjust posture and shift weight off of the spinal column
• Providing some added spinal support to take pressure off of weakened or injured muscles
• Moderately limiting range of motion to allow for some bending and twisting. For instance, while wearing a flexible brace, it may be possible to bend forward enough to touch the top of the knee, but not past the knees
• Reducing micro-motion at a loose or weakened joint through compression of the torso or pelvis (especially in lumbar and sacroiliac joint belts)
• Relaxing tense muscles through the warmth of the brace
