O'Neill Hyperfreak Fire 5/4 Chest Zip

O'NEILL HYPERFREAK FOUR 5/4 CHEST ZIP

When Cold Hawaii calls, it's about being in the water – not on land.

The O'Neill Hyperfreak Fire 5/4 Chest Zip is an uncompromising winter wetsuit designed for cold conditions where maximum warmth is required combined with extreme flexibility. The Hyperfreak Fire series builds on O'Neill's most mobile platform and adds their warmest thermal lining, so you can surf longer without losing freedom of movement.

The 5/4 construction provides extra insulation around the body where warmth matters most, while the lightweight, flexible construction in the arms and shoulders ensures free paddling and natural movement. The FUZE Chest Zip entry reduces water ingress and provides a close, anatomical fit that works with the body – even during long sessions in cold water.

In Cold Hawaii, when the conditions are good, reliable gear means everything. The Hyperfreak Fire 5/4 is made for those days when the cold is harsh but the conditions are too good to stay on land.

More warmth. More flexibility. More time in the water.
