Comfortable for all-day wear, the Coretech 621 SI Belt is great to use for maximum support at home and at the office. It helps stabilize and reinforce the SI joint during daily activities.

This belt compresses and supports sacroiliac joints, helping to treat muscle pain and soreness. Thumb loops and hand pockets make it easier to secure straps during use.


Adjustable And Secure Fit

The Pulley System on the back allows to adjust compression levels as needed and provides rigid back support.


Designed to make all-day use more easy and more enjoyable with a soft inner lining. The thin and breathable material prevents any build-up of moisture.
