Size L (89cm-102cm) Quantity 1 [3-in-1: Lumbar Support/Pelvic Care/Training] This lumbar corset is an all-in-one back support belt that combines three major functions: lumbar protection, pelvic stabilization, and training assistance. It comprehensively addresses common modern problems such as lower back pain, pelvic misalignment, and poor posture. This single belt achieves the functionality of three. It caters to diverse needs, including office workers, those needing postpartum pelvic care, and training enthusiasts. [New Pulley Design, Amazing Support] The corset's pulley design allows for instant tightening with a single touch. The collaboration of a movable pulley design, adjustment straps, and high-strength adjustment strings (cords) precisely controls the support force on the lower back. The pulley's labor-saving mechanism provides secure fixation with minimal effort. The back support belt is ergonomically designed to firmly wrap the waist and abdomen, effectively reducing the burden on the lumbar spine. It is a reliable product recommended by chiropractors and physical therapists. [Thin, Highly Breathable, Comfortable to Wear, Durable and Portable] The pelvic belt uses nylon mesh material and 3D support plates. While maintaining excellent support, it is thin and highly breathable, making it comfortable for long-term wear. The soft sponge mesh pad sewn inside the back pain corset prevents slippage and shifting during wear. It reduces excessive pressure and digging into the lower back, firmly protecting the waist. Made with high-quality materials, it is highly durable, does not lose its shape, and can be machine washed in a laundry net. It weighs only 180g and is lightweight and foldable. It can be stored in a bag, making it convenient to carry when going out. [Unisex, Suitable for All Occasions] For those suffering from lower back pain, pelvic misalignment, postpartum pelvic laxity, and poor posture. By using the back pain corset for 10 minutes a day for 20 days according to the instructions, you can experience positive changes in your body. It is especially recommended for those who stand for long periods, such as customer service staff, medical professionals, drivers, construction workers, and office workers, those who are prone to sudden lower back pain, and middle-aged and elderly people concerned about their back health. 婕5..
