Never given the Anti static quality of Nomex a thought either.
Nomex is not the only fire fabric out there
Besides protection from direct flame, CarbonX® withstands heat extremely well. For example, at approximately 600° f., the leading FR fabrics burn, begin to shrink while charring, then crack and decompose. This is all in about 10 seconds. Under the same conditions, CarbonX is not affected in any way. It even disburses the heat energy and will take about 60 seconds before the heat will start penetrating the next layer of fabric.
