The Thermal Vent Lumbar Support Wrap gives a combination of support, compression, and heat therapy to help treat and prevent lower back pain. This wrap is also very effective at reducing the symptoms of sacroiliac joint dysfunction, back muscle strains, lower back pain, lumbar disc injuries, as well as a wide variety of other back injuries. This wrap utilizes flexible internal stays that provide additional support in addition to preventing the sides from rolling up during wear. There are two adjustable side straps that can be used to provide extra compression therapy as needed. In addition to exceptional support, the Thermal Vent Lumbar Support Wrap is engineered with Micro Ventilated Thermal Technology that is crucial in rehabilitating injured back tissue. Essentially, this technology uses the natural body heat of the wearer to provide warmth and heat therapy to increase pliability and elasticity of muscles and tendons. The layered thermal lining has a soft, nylon material that is in contact with the skin. This material helps wick away moisture and releases moist air to keep the skin comfortable. There is also a micro ventilated, breathable membrane that captures, retains, and applies the natural body heat to the back in the form of heat therapy.
