The LumboTrain® back brace provides active support and stabilization for the lumbar spine while helping to relieve pain and pressure. Designed for chronic or acute lower back discomfort, its circular knit compression material reduces pressure by engaging the core muscles, improving posture and stability. The rigid viscoelastic lumbar pad, combined with multiple massage nubs, stimulates circulation, activates specific pressure points, and gently massages tissues to relieve tension, reduce pain, and support overall lumbar function during movement. Size 3 = 90-100cm waist circumference.
