O'Neill HyperFire 4/3mm Men's Chest Zip Steamer Wetsuit – Black

The O'Neill HyperFire 4/3mm Men's Chest Zip Wetsuit is a premium cold-water steamer designed to deliver an exceptional combination of warmth, flexibility and lightweight performance. Formerly known as the HyperFreak Fire, the HyperFire takes O'Neill's high-stretch wetsuit platform and adds advanced thermal technology for surfers who want maximum freedom of movement without sacrificing warmth.

With 4/3mm thickness, a FUZE chest zip entry, TB4X and TB4 materials and O'Neill's graphene-infused TB4 Firewall lining, the HyperFire is built for colder surf conditions and longer sessions when both heat retention and paddling freedom matter.

TB4X Flexibility & TB4 Warmth

O'Neill uses TechnoButter 4X (TB4X) through the arms, back and shoulders, providing an exceptionally lightweight, soft and flexible feel through the areas where surfers need the greatest freedom of movement.

The chest and legs use TechnoButter 4 (TB4) with O'Neill's lightweight ENVY foam rubber core, balancing stretch with the additional warmth required through the body and lower half of the wetsuit.

This combination helps reduce restriction through the shoulders while paddling, making the HyperFire particularly appealing for surfers who dislike the heavier feel traditionally associated with a warm 4/3mm winter wetsuit.

Graphene TB4 Firewall

Inside, O'Neill's TB4 Firewall uses recycled graphene fibres combined with a thicker pile to increase warmth in cold conditions. As body heat warms the graphene fibres, they conduct heat back towards the body to help retain warmth during your session.

The Firewall liner is also designed to dry quickly. O'Neill states that after hanging the wetsuit following a surf, the Firewall lining can be touch dry in approximately 30 minutes.

FUZE Chest Zip Entry

The HyperFire uses O'Neill's popular FUZE chest zip system, featuring a free-floating zipper panel and anti-flush barrier with drain holes.

This design creates an effective seal to help reduce flushing and keep warmth inside the wetsuit while still allowing relatively easy entry and exit.

Fully Taped Sealed Seams

The seams are glued and blind stitched (GBS) to create a durable watertight seal, then reinforced internally with recycled TB4X taping.

O'Neill's Minimal Seam Design uses larger panels and fewer seams to improve flexibility, fit and durability while reducing unnecessary restriction through the wetsuit.

A double-seal neoprene collar adds comfort around the neck, while durable Krypto Knee Padz provide protection through a high-wear area without compromising flexibility.

Why You'll Love It

The real strength of the O'Neill HyperFire 4/3mm is that it tackles the traditional compromise between warmth and flexibility.

A thicker winter wetsuit can keep you warm but often introduces additional weight and restriction. O'Neill addresses this by using highly flexible TB4X across the arms, shoulders and back, while concentrating TB4 and the thermal graphene Firewall where warmth matters most.

Add the FUZE chest zip, fully taped GBS seams, minimal panel design and double-seal collar, and you have a serious performance-oriented 4/3mm steamer for surfers who want to stay warmer without giving up paddling freedom.
