IMPACTO Air Belt® Lumbar Support Belt. Palm-grip self-contained aspirator with pressure release valve regulates air intake. Contoured inter-connected air chambers. Lightweight moisture absorbing inner lining. Durable nylon outer cover. Three adjustable straps provide additional support. HOW IT WORKS Often when the lower back starts to feel stiff or tight, a nagging backache is usually on the way. But worse yet, is the serious sprain that can occur during normal activities such as reaching, bending low, lifting or twisting. When you pump air pressure into the Air Belt, the low back muscles respond to static stretch, thus alleviating spasm and allowing muscles to assume their natural resting length to become less prone to injury.
To determine sizing use waist measurement and add 2" if belt is worn over clothing. For LS, DIP & DUAL use hip measurement.
