The Back Flex Lumbar Brace provides vectored compression to the lower back region. The ergonomic pulley system draws the tall lumbar panel forward into the spine, relieving tension on the supporting muscles and ligaments. The Back Flex includes rigid front panels for greater posture control and pain relief than the Vector Back Brace provides. Vented side panels, hypoallergenic materials, and flexible front and back panels allow the brace to be comfortably worn for hours of pain relief at a time. Two hot/cold therapeutic gel pads are included with the brace and fit into a pocket in the lumbar panel. Place the gel pad in the microwave for soothing heat, or in the freezer for pain-relieving cold.
