The CoreFX outer fabric delivers very high tensile strength and high tear strength. When used in combination with our new 3D moisture barrier and thermal lining, it delivers high radiant heat performance and very good breathability. CoreFX does not break open when subjected to a double flashover.

Choosing Core FX gives you more strength and durability than other options, but with slightly lower thermal performance and similar breathability when in this system.
