This lumbar support back brace delivers full 360°stability using 3 memory-aluminum stays and 2 rigid support plates positioned to reinforce the lower back and sacral area. Designed for everyday wear, it features soft, breathable fabric that wicks moisture and reduces skin irritation while maintaining structural integrity. Adjustable elastic straps with finger loops allow for precise Tension control and easy self-application without assistance. The contoured shape follows natural spinal curvature, offering targeted compression to the lumbar region without restricting hip or torso movement. It fits securely during dynamic activities like lifting, bending, standing for extended periods, or driving, and remains stable without rolling or shifting. Sizing is based on waist measurement at the navel, covering a broad range from 25. 6 in. to 65 in. to accommodate diverse body types. The brace supports recovery and daily function for conditions including general lower back strain, herniated disc discomfort, and sciatica-related pain. Its low-profile design layers comfortably under most clothing and requires no tools or special instructions for use. Size: large.
