F.U.Z.E. Closure and anti-flush protection

The suit features F.U.Z.E. Closure, a chest-entry system designed to provide a secure upper-body closure.

It is supported by a 360 Degree Barrier with Drain Holes, which helps reduce water entry while allowing excess water to drain out.

Minimal Seam Design reduces the overall number of panel connections, supporting flexibility and helping limit potential water entry points.

Extra 0.5 mm of thickness

The 5/4+ designation means the wetsuit includes an additional 0.5 mm of neoprene for extra warmth.

This provides more thermal insulation than a standard 5/4 mm construction while maintaining the flexible feel of the Hyperfreak range.

Integrated hood for colder sessions

The w/Hood version features an integrated hood for additional thermal protection around the head and neck.

This makes the men's O'Neill Hyperfreak 5/4+ Chest Zip w/Hood better suited to long sessions in cold and demanding conditions.

Fully taped and sealed seams

The wetsuit uses Glued and Blind Stitched Seams combined with Recycled TB3X Fully Taped Seams.

The fully taped construction reinforces the panel connections and helps reduce water penetration through the seams.

Aqua Alpha lamination and knee protection

The neoprene is laminated using Aqua Alpha Solvent Free Neoprene Lamination, a solvent-free lamination process.

The knees are reinforced with Krypto Armor Knee Padz, increasing durability in one of the highest-wear areas of the wetsuit.
