Pressure belt with an adjustable design that supports the lower back with a large pressure plate. - Model Name: W Lumbar Corset Pressure Belt - Color: Black - Features: Supports the lower back with a large pressure plate - Size: Adjustable - Design: Mesh material and stretch bands I bought this because my lower back pain was severe, and while it did provide support, it didn't fit the location of my pain, so I haven't used it much. Please consider it if you have lower back pain. Thank you for looking.
