Fit for Hips:76-119cm/30"-47", Belt Length:117cm/46" Belt width: 12 cm. Non-restrictive design for men and women.RELIEVES JOINT AND INflammATION PAIN - The sacral belt helps stabilize the sacral joint (or "SI joint") hypermobile or inflamed, and relieves pain in the pelvic, lower back and/or leg nerve (sciatica) caused by a functional disorder of the SI joint. We strongly recommend that you wear the SI joint belt for at least two weeks day and night.Lightweight and durable - The perforated neoprene used in the inner belt is lightweight, breathable and does not fray. Designed to be comfortable day and night. The slim design is discreet and easy to hide under clothing. Make sure you do not tighten the belt too tight and wear it on the hips of the lower back. This can cause it to remain unnoticed during your daily activities.NON-SLIP BACK SI SUPPORT BELT: The sacral sacral belt with unique comfort on the back of the belt gives your body extra flexibility and comfort. So you can wear it at any time. The non-slip silicone strips on the inner strap prevent the belt from slipping. The SI belt can stay in place to maintain pain relief during light physical activity. However, during the recovery phase, intensive physical activity is not recommended.DOUBLE ADJUSTMENT AND MAXIMUM COMFORT - The SI joint belt has been designed to wear it for longer periods of time, which is the success for recovery and pain relief. The all-round "double strap" design provides controllable compression and the secondary straps allow you to adjust the amount of additional compression required for certain painful or inflamed areas. The breathable fabric allows air and moisture to penetrate.
