What this is (and what people call it)

This is a lumbar support brace — also called a back support belt, lower back brace, or lumbosacral support. It wraps around the lower back and abdomen to provide compression and postural support. It is not a rigid brace — it is a flexible, semi-rigid support designed for daily wear and activity.

Add a hot/cold therapy gel pad (Part No. GB19028) to your order for targeted thermal pain relief. The gel pad fits into the back pocket of the brace and can be used warm or cold to help manage inflammation and muscle soreness. Select the add-on option in the variant selector above.
