O'Neill's Techno Butter 4, Techno Butter 4x, and Techno Butter 4 Air Firewall combine in the unreal Psycho Tech chest zip for incredible warmth and freedom.
TB4x, thee ooiest, gooiest neoprene O'Neill has, makes up the arms, shoulders, and chest for non-restrictive paddling and taking-off. TB4 Air Firewall in the chest quickly traps your body's generated warmth, which is efficiently retained by graphene fibers in the suit's interior jersey. Those fibers radiate the heat throughout the suit, keeping you warmer, longer.
