The Lumboheat™ is made from premium breathable neoprene-like material that's soft against your skin yet durable enough for daily use. The fabric stays comfortable even during extended wear and wicks away moisture so you don't overheat.
The expandable 3-way adjustable strap system fits waist sizes from 28" up to 60", with a main hook-and-loop strap plus two flexible side straps for a custom, secure fit. Whether you're slim, average, or plus-size, it conforms to your body shape and stays in place—no slipping, no rolling—even when you're bending, twisting, or moving around.
It's washable (just remove the battery pack), lightweight at about 1.5 lbs, and slim enough to wear discreetly under clothing.
