【Unique Design】This waist belt is made of breathable, non-slip material, ensuring a secure and comfortable fit without slipping. It provides stable support for the lower back and sacroiliac joint, reducing nerve compression and muscle tension. 【Breathable, Lightweight, and Pressure-Free】Made from neoprene and elastic composite materials, the belt ensures stable support and breathable comfort. The breathable inner layer effectively wicks away moisture, preventing stuffiness or friction after prolonged use. The soft, snug edge design prevents it from rolling up or creating pressure points. 【Stable and Secure】Unlike traditional single-layer elastic bands, this waist belt uses a double support system. The two-way rubber outer layer allows for adjustable pressure according to individual needs, while the non-slip inner layer fits snugly against the waist, preventing it from slipping. The ergonomic design ensures even pressure distribution across the lower back, pelvis, and tailbone. 【Suitable for Multiple Occasions】Whether you sit in an office for long periods or stand for extended periods, this sciatic nerve pelvic belt is suitable. Suitable for both men and women, it can be discreetly worn under clothing. Especially suitable for postpartum women, those with back discomfort, or those who sit for long periods. 【Size】Three sizes are available: 110 cm, 125 cm, and 140 cm. Please choose the size that suits you best.
