1051 Mesh Back Support Brace protects workers from strains and body aches while lifting and moving heavy objects. Brace is made of a two-stage closure system: hook-and-loop front that conforms to your body and innovative, power panel positioners with hook-and-loop closures that tighten fit to activate maximum back support. Lumbar pad reduces the amount of pressure on your lower spine when lifting objects to avoid injury on the job. Outer shell is made of breathable mesh to enhance airflow ventilation and decrease sweat production.
