The lumbar support belt features a medical ergonomic design with a 360° circumferential fit. It is designed according to the lumbar structure, offering lower support and upper push-up. Four powerful bionic cartilage components provide strong support, fitting the curve of the lumbar spine and bearing its pressure. Graphene temperature-sensitive heating warms the entire waist. The belt includes an electric waist warmer with a rechargeable power supply and provides up to 8 hours of comfort without excessive cinching.
