Dr Ho's Therapy Belt Enjoy both muscle-relaxing warmth and support while you're on the go. Back support belt has self-conforming air cushions to provide support for low back, plus an extra large heating area that provides relief where you need it. Just drop the included heat pad (8x 6) into the thermal pocket for 20-30 minutes of soothing heat. Reusable pad is reset by dropping into boiling water (it will activate again once you snap the metal discs inside). Lightweight, snag-resistant material can be worn underneath clothing. Belt approx. 48x 8 with Velcro closures; one size fits most. Imported.
