Horizon 627 Lumbar is the slimmest among Horizon products. It gives great support and helps with pain. It uses the SlickTrack tightening system, which is well-liked. This system applies pressure all around, making the trunk stable and easing specific pain for people getting recovered from surgery or injury. It fits waists from 24 to 70 inches and can be adjusted to fit. It can be switched to the Horizon PRO (Pain Relief Orthosis) for treating ongoing back pain, just like other Horizon braces.
