We are very excited about the latest addition to the O'Neill wetsuit range. The O'Neill Hyperfreak Fire 5/4+ focuses on extreme warmth, high performance, increased durability, and comfort. Even better, the neoprene is made from recycled materials , making the suit more sustainable and at the same time offers the best flexibility and heat retention possible. These technologically advanced materials plus water-tight Fluid Seam construction have created a new cold water legend. Fire red-hot heat takes the innovative Hyperfreak legacy to the next level. Key Features plus 0.5mm for additional warmth anti-flush barrier  drainholes prevent water from entering the suit minimal seam design recycled materials - TB4, TB4X, TB4 Firewall tapered fit wrist and ankle seals PL wrist and ankle seals Krypto knee padz double super-seal collar key pocket with loop Construction glued & blind-stitched exterior fluid seam weld TB4x arms & entry TB4 Firewall front, back, thigh, butt TB4 top shoulder & low legs The new Technobutter 4 material explained: TB4: Technobutter 4 builds on the legendary Technobutter 3, the next evolution of the jersey introduces recycled yarns infused with graphene for increased wear strength and heat retention. TB4X: Technobutter 4x goes beyond the gooey and soft feel of TB3x. Recycled graphene fibres line the jersey allowing for incredible stretch with added strength and warmth retention, all with a new look. TB4 Firewall: The all new Technobutter 4 Firewall utilises the recycled graphene fibres at a thicker pile to create a fire hot feedback loop. As the body heat warms the graphene fibres they conduct the heat back into the body.
