What separates the Fire from a standard Hyperfreak is its TB4 Firewall construction — a graphene-infused thermal layer that traps and feeds body heat back into the suit. This 5\/4mm+ Chest Zip model adds a fixed hood for full-head coverage in bone-chilling water.\u003c\/p\u003e\u003ch2\u003eDetails\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeoprene \/ materials:\u003c\/strong\u003e Graphene-infused TB4 Firewall and TechnoButter 4 (TB4) jersey, built on a base of recycled oyster shells and eco carbon black infused neoprene.
