Product Description 【Unique Design】 The belt is made of breathable material with a non-slip design, ensuring it stays securely in place and does not slip. This belt provides stable support for the lower back and sacroiliac joint, reducing nerve compression and muscle tension. 【Breathable, Lightweight, and Pressure-Free】 Our belt is made of neoprene and elastic composite material, ensuring stable support and breathable comfort. The breathable inner structure effectively wicks away moisture and heat, preventing stuffiness or friction after prolonged use. The finished edges ensure a soft, snug fit and prevent it from rolling up or creating pressure points. 【Stable and Secure】 Unlike traditional single-layer elastic belts, this belt uses a double support system. The two-way outer elastic band allows for pressure adjustment according to individual needs, while the non-slip inner material firmly molds around the waist, preventing it from slipping. The ergonomic design ensures even pressure distribution across the lower back, pelvis, and tailbone. 【Suitable for Various Occasions】 Whether you sit in the office for long periods or stand for extended periods, this pelvic belt for sciatica nerve is suitable. Suitable for both men and women and can be worn discreetly under clothing. Especially suitable for postpartum women, people with back problems, or those who sit for long periods. 【Size】 Available in three sizes: 110 cm, 125 cm, and 140 cm. Choose the size that suits you best.
