C3 fabric
The Nano C3 is a new C3 fabric upgraded with improved ESD and Nano-Seal technology. Manufactured domestically, it uses the same proven filament polyester yarns that are in the current C3. The new fabric contains a new ESD yarn that yields improved surface resistivity results according to AATCC 76. The addition of the Nano-Seal technology changes the fabric at the molecular level to significantly reduce particulation. Aesthetics and breathability are not affected by the addition of the Nano-Seal technology.
