Bauerfeind's LumboTrain back braces and supports stabilize and massage the muscles of the lower back, while treating pain and tension with a comfortable breathable knit fabric. LumboTrain braces help reduce back pain and improve mobility and reduce the need for pain medicine. A comfortable pad in the support provides a stimulating massage effect to the muscles of the lower back with every movement to help to reduce tension and relieve pain. Velcro fastenings and practical hand straps allow for easy application and adjustment, even for people with arthritis. The soft knit fabric is breathable and skin-friendly, unlike Neoprene and other inferior materials. And, it's machine washable in the gentle cycle, which helps the support maintain its elasticity and original fit. The stretchy, three-dimensional fabric automatically conforms to any body shape, so you get a natural fit. Soft edges at the outer brace will not dig in to your skin. Walk, sit, stand and run with the back support you need and avoid painful back tweaks with LumboTrain back braces and supports by Bauerfeind. Material: Knit Fabric, Viscoelastic.
