UltraSoft® AC represents the natural evolution of the UltraSoft® fabric line, delivering unsurpassed long-staple comfort when comfort is a concern for your employees. The exceptional softness found in UltraSoft® AC derives from a blend of 88% long-staple/ 12% high tenacity nylon, as well as our advanced softening technology. Like UltraSoft®, the UltraSoft® AC line is guaranteed flame resistant for the life of the garment in either high-temperature industrial or home washing procedures. It also offers enhanced protection from electric arc and flash fire exposures, as well as multipurpose protection from electric arc flash, flash fire, molten ferrous metal and welding exposures.
