Feature: Dual Adjustment Design – The waist belt allows you to freely adjust to your preferred tightness, enabling targeted pressure adjustment in different areas. Exquisite Workmanship: The sacroiliac belt is made of high-strength, body-conforming material that flexes naturally with movement. The high-elastic waistband secures the brace firmly to the body and minimizes shifting, preventing slippage during walking, sitting, standing, or other physical activities. Maintains shape and integrity even after extended use. Non-Slip & Durable: Integrated non-slip silicone strips ensure the brace stays securely in place without riding up on the hips. Designed for comfort during daily wear — suitable for sitting, sleeping, and light exercise. Low-profile design allows it to be worn discreetly under clothing. 100% Satisfaction Guarantee: If you have any questions, please — we’re happy to help. Note: Actual color may vary slightly due to lighting conditions. Please allow 1–3 cm measurement tolerance. Material: Neoprene Size: 109 cm / 140 cm Package Includes: 1 × Back Support Belt
