Features: brand new and high quality Lightweight and breathable waist for protection belt, aimed at the protrusion of the lumbar disc. The 4 support plates are evenly distributed: support the protruding lumbar intervertebral disc, assist the lumbar spine to return to normal curvature, and reduce lumbar spine compression. Cartilage support and anti-slip: The cartilage support design is adopted on both sides of this product, which is flexible and the cartilage effectively prevents the lumbar support from slipping off. The reverse C-shaped thrust restores the 26 curve of the waist: 26 arc steel plates support the deformed lumbar vertebrae in rows and disperse the pressure on the lumbar spine. Double-layer straps double the effect: the outer double-layer afterburner belt increases the intra-abdominal pressure and doubles the support effect of the steel plate. Summer waist for protection, light and breathable: large mesh breathable design, breathable and wicking, skin-friendly, comfortable and not stuffy.
