The Champion C-443 is made from Airmesh fabric, a strong 
     yet lightweight non-latex polyester-spandex blend open knit
     material. Airmesh offers breathability, elasticity,
     compression and comfort. It is well suited for long term wear,
     wear in warmer climates, and ideal for those who are allergic
     to or irritated by neoprene fabric.
