belt length: 109cm; . Unrestricted design for men and women. RELIEVES JOINT PAIN & REDUCES INFLAMMATION: The sacroiliac belt helps stabilize the sacroiliac joint that is hypermobile or inflamed, and reduces pelvic, lower back and/or leg pain (symptom of sciatica ) caused by SI joint dysfunction. We strongly recommend that you wear the belt day and night for at least two weeks. Lightweight and Durable: The perforated neoprene used in the inner waistband is lightweight, breathable and pilling resistant. Designed to be worn comfortably day and night and the slim design is low profile and easily concealed under users clothing. Make sure you don't overtighten the belt and wear it on your lower back, which can make it invisible while doing your daily activities. NON-SLIP BACK SUPPORT BELT: The sacroiliac belt with a unique curved waistband comfort gives your body the extra flexibility and comfort to be worn at all times. Non-slip silicone strips on the inner waistband prevent the waistband from slipping up and down. The belt may remain in place to maintain pain relief during light physical activity, but vigorous exercise is discouraged during the recovery period. DUAL ADJUSTMENT AND MAXIMUM COMFORT: The hinged belt is designed to be worn for long periods of time, which is key for recovery and pain relief. The wraparound "double belt" design provides controllable compression and the secondary straps allow you to customize the amount of additional compression needed on sore or inflamed areas. Breathable fabrics allow air and moisture to pass through.
