Comfortable to wear under clothing: Made from elastic 4way stretch material using 3D knitting technology, it offers varying compression levels for an fit, breathability, and comfort. The inner layer is crafted from soft velvet fabric, providing a silky, babyskinlike feel for effortless wear. 3. Prevents back injuries: Equipped with 2 elastic straps, the back support delivers targeted compression to the lower back, guarding against injuries from weightlifting, prolonged standing or sitting, housework, or workrelated tasks. Wearing it alleviates pain associated with strained waist muscles, herniated discs, sciatica, scoliosis, and more. 4. Thoughtful design details: Two nonslip bands on either side of the waist prevent the support from rolling up during sitting, bending, or other movements. The widened Velcro fasteners on the elastic straps ensure strong adhesion. Made from skinfriendly PVC material commonly used in clothing, it won't irritate your skin or damage your clothes.
