The Champion C-420 is a medium duty controlled stretch elbow support 
      that can be worn for mild sprains and strains, or for weakness due 
      to previous injury, repetitive motion or over-exertion. It is made 
      from Airmesh fabric, a strong yet lightweight non-latex polyester-spandex
      blend open knit material. It offers breathability, elasticity, 
      compression and comfort. It permits continued activity and prevents re-injury. 
      Opening over elbow helps support maintain it's correct position
      Encircling support strap prevents painful overuse of underlying muscles
      Airmesh fabric absorbs perspiration for all day wearing muscles
