O'NEILL MENS HYPER FIRE X CZ FULL 4/3MM CHEST ZIP STEAMER 2026

O’Neill Men’s HyperFire X Chest Zip Full 4/3mm Steamer 2026 is built for surfers pushing into cold, demanding conditions who want elite warmth without compromising flexibility. Sitting at the very top of O’Neill’s wetsuit lineup, the HyperFire X blends cutting-edge materials with precision construction to deliver peak performance in extreme environments.

A TB4X super-stretch upper body provides outstanding paddling freedom and easy entry, while Air Fire Wall panels across the chest and back trap insulating air to minimise heat loss. Inside, a graphene-infused Fire Wall liner keeps you warmer and drier—and is touch dry in around 30 minutes after your session. Externally, Fluid Weld seam sealing locks warmth in, reinforced with internal critical taping for durability through heavy winter use.

Finished with O’Neill’s proven FUZE chest zip system, this 4/3mm HyperFire X offers a secure anti-flush seal with efficient drainage, making it ideal for long, high-output sessions in cold water. Built with O’Neill Blue materials, it also reflects a strong commitment to sustainability.
