◉【Enhanced Support with 8 Memory Springs and 1 Plate】This back support belt features 8 lumbar 3D support bones that perfectly fit the waistline, firmly maintaining posture and supporting the correction of proper posture. Additionally, a single support plate on the back firmly secures the lower back and back! ◉【Double-Layer Belt for Secure Fastening】The double-layer belt design with elasticity prevents slippage and provides a moderate level of compression, enhancing the fixing power. It is easy to move around and less likely to shift during work or sports. This corset is highly recommended for those with chronic lower back pain. It firmly protects the lower back during tasks that require physical exertion. ◉【Excellent Breathability】The sides of the waist use a see-through mesh material to prevent uncomfortable sweating. The inner surface of the waist supporter uses a 3D three-dimensional mesh structure to ensure breathability while providing a firm hold. Also, it is a wide-width design, not a sports type that over-tightens, but is specialized for daily use and does not restrict movement. ◉【Ergonomic Fit】This product increases intra-abdominal pressure and disperses the force concentrated on the lower back, preventing injuries and pain, or alleviating existing pain. Also, the wide belt, with a maximum width of approximately 22cm (back), wraps around from the waist to the abdomen, providing a 360° fit around the waist. It is unisex, and the tightness of the corset can be adjusted while wearing it.
