A special premium gel pack can be frozen, while still being pliable for superior comfort, or can be heated in the microwave. In either case, the premium gel pack can then be placed into the sleeve of the posterior panel to enhance the therapeutic benefit of the BioBack.

- Standard (fits 22" to 50" waists)
- Large (fits 51" to 78")
