Relieves lower back pain - The back support features 4 memory aluminium struts (four times harder than common PP strips) and 2 steel springs along the waist, providing 360-degree vertical support for the lower back. This design helps prevent excessive rolling of muscles and reduces pressure on intervertebral discs. Comfortable to wear under clothes - Constructed with 4-way stretch elastic material and 3D knitting technology with varying compression levels for an excellent fit, breathability, and comfort. - The inner layer uses velvet fabric for a silky touch, making it suitable to wear directly against the skin when placed under clothing. Prevents back injuries and relieves discomfort - Two elastic bands offer additional compression in the lower back area to help prevent injuries from weightlifting, long standing or sitting, and housework. - Helps relieve waist pain, herniated discs, sciatica, scoliosis, and related conditions when wearing the back strap. Thoughtful design for stability and skin compatibility - Two non-slip bands on the sides prevent the belt from rolling up during sitting, bending, or other activities. - A wider Velcro fastener with two elastic bands provides stable closure. The adhesion uses PVC material commonly used in clothing, delivering strong grip without scratching skin or damaging clothes. Use scenarios - In the gym or during weightlifting to protect the lower back and support proper form. - All-day wear at work or at home for posture support during desk tasks, chores, or extended standing. - Travel or long drives to maintain back stability during extended sitting.
