Sacroiliac (SI) Joint Pain Relief With the BackWonder SI Support Belt

Lower back pain caused by sacroiliac joint dysfunction can make sitting, walking, or daily movement uncomfortable. The BackWonder Sacroiliac (SI) Support Belt is designed to deliver targeted SI joint support, stability, and lasting comfort for people struggling with SI joint pain, pelvic instability, or chronic lower back discomfort.

Designed by Founder and Physical Therapist Richard Shutes, this SI belt was engineered to address the root mechanics of sacroiliac joint pain rather than masking symptoms.


Why the Sacroiliac Joint Causes Lower Back Pain

The sacroiliac joint connects the spine to the pelvis and plays a critical role in load transfer and movement. When this joint becomes inflamed, unstable, or misaligned, it often results in:

  • Lower back pain near the hips

  • Pain when sitting or standing for long periods

  • Discomfort during walking, lifting, or bending

  • Radiating pain into the hips or glutes

Proper compression and stabilization of the SI joint is one of the most effective non-invasive ways to reduce pain and improve daily function.


Key Benefits of the BackWonder SI Support Belt

Effective SI Joint Compression and Support

The BackWonder SI belt delivers targeted compression directly to the sacroiliac joint, helping stabilize the pelvis, reduce joint stress, and relieve lower back pain caused by SI joint dysfunction.

Comfortable, Secure Fit That Stays in Place

A wide neoprene foundation strap with moisture-absorbent lining and non-slip panels prevents shifting, bunching, or rolling during movement. You get firm support without restriction.

Easy to Put On and Adjust

The offset buckle design and double-side-pull elastic cinch straps allow for quick application and precise tension control. Adjust once and move confidently throughout the day.

Designed for Sitting, Standing, and Active Use

Whether you work at a desk, drive frequently, or live an active lifestyle, this SI belt is built for all-day wear without digging into your thighs or hips.

Optional Enhanced Lumbar Support

Pair the SI belt with the BackWonder inflatable lumbar pillow for added lower back comfort during prolonged sitting or driving.


Product Features

  • Wide neoprene foundation strap for comfort and durability

  • Moisture-absorbent lining with non-slip grip panels

  • Double-side-pull elastic cinch straps for controlled compression

  • Innovative offset buckle for easy fastening

  • Heavy-duty elastic materials for long-term support


Why Choose the BackWonder Sacroiliac Support Belt

Unlike generic back braces, the BackWonder SI Support Belt was created by a physical therapist who understands the biomechanics of SI joint pain. Every design element is intentional, from the placement of compression to how the belt moves with your body.

This belt is ideal for:

  • SI joint dysfunction

  • Pelvic instability

  • Lower back pain from sitting or lifting

  • Postural strain

  • Everyday support during work or activity


How to Wear the BackWonder SI Support Belt Correctly

  1. Wear the belt over underwear or lightweight clothing. Cotton or moisture-wicking fabrics work best.

  2. Position the belt low, below your hip bones. The center of the cinch straps should sit just above the buttocks.

  3. Offset the buckle slightly to one side for comfort.

  4. Thread the belt through the metal buckle, pull snug, and secure with the hook-and-loop closure.

  5. Pull each elastic cinch strap firmly and secure them in place.

  6. Move around and sit down to confirm the belt feels supportive without cutting into your thighs.

Proper positioning is key to effective SI joint relief.

This belt is sturdy, thicker material than some I've used in the past. It's not very long (height-wise), which makes it a bit more discreet under clothing. It gave good support and decent pain relief!

I do like this. I have some sacral instability at times. This device is really helpful to get through those. It is comfortable enough to fit under loose pants. I still wear leggings or something fitting under to help with skin bunching or rubbing. This device does not rub or bunch the skin like another stability belt I have. I do like this one better.

Size seems to run a trifle large. If between sizes go for the smaller one. I bought two of these. 40" hip was at edge of size range between medium and large. The medium ended up working much better. GNR is prominent brand displayed, not Backwonder.

The hook-and-loop (velcro) held up very well. The loop back of primary belt helped with the hold and adjustment.

It is not very wide (unlike most of the competitors). Some secondary straps to make it wider around sides would have been nice.

This has lasted 5 years! Amazing compared to others where the Velcro dies, or body strap curls up all of the time (the disadvantage of others that use wider strap). However, eventually it started fraying around edges.
