Available in sizes Small through XXXL and optionally bundled with a hot/cold therapy gel pad for enhanced pain relief.
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.
