This is the third Sacroiliac Belt I have tried, (not counting the wrong size one I bought from Mars initially.) It is far more comfortable than the other two brands I bought and is lighter. The velcro matches up well, keeping it from scratching my skin. In addition this belt has some silicone lines on it that help keep it in place.
On top of all this, when the first belt I ordered was too small, Mars gave me instant credit for it and got the replacement to me quickly.
I am super tired of having sciatica but this belt has helped and I would gladly order from Mars again
