A new open-cell urethane foam layer is breathable, more comfortable, moisture-wicking, and hypoallergenic (so it can be worn directly against the skin). Plus, it conforms to body curves better. The problem with most sacroiliac belts is that they move upward on the body because there is no way to attach them. Due to the new urethane foam's tacky nature it grips so well that it will not move – even on the most active people.

The non-elastic inner layer mimics the function of the sacroiliac ligaments by creating a stop-point at the joint’s normal end of range of motion.
