O'Neill Hammer 3/2 Chest Zip Full Black

O'Neill Hammer 3/2 Chest Zip Full Black

The O'Neill Hammer 3/2 Chest Zip Full is part of the Hammer Series — a lineup built to perform in every condition. The 3/2mm thickness provides reliable thermal protection for transitional water temperatures, while the F.U.Z.E. chest zip closure minimises water entry and heat loss. Constructed from 100% Super Stretch UltraFlex neoprene, the Hammer 3/2 is now fully double-lined with minimal seam design for superior comfort and durability.

Key Features

• F.U.Z.E. Closure (Chest Zip) – O'Neill's chest zip system seals against water flushing while maintaining the flexibility of a zipperless entry.
• Seamless Paddle Zones – Critical areas across the shoulder and underarm are seam-free for unrestricted paddling movement.
• Double Super Seal Neck – Dual-layer neck seal prevents cold water from entering at the collar.
• 360° Barrier with Drain Holes – Full perimeter barrier at the wrists and ankles with drain holes to expel trapped water.
• Krypto Knee Padz – Reinforced knee panels resist abrasion from board contact and improve grip.

Construction

• 100% Super Stretch UltraFlex Neoprene – Full-suit flexibility and warmth without compromising movement.
• Double Lined – Enhanced durability and insulation throughout the suit.
• Minimal Seam Design – Fewer seams mean fewer cold spots and less chafe.
• Flatlock Stitched Breathable Seams – Where seams exist, they are flat-stitched for comfort and durability.

Frequently Asked Questions

What water temperature is a 3/2mm wetsuit designed for?

A 3/2mm full suit is typically suited for water temperatures between 15°C and 20°C, though individual tolerance varies. The 3mm core provides insulation for the torso and core, while 2mm panels on the limbs allow for greater flexibility.

What is the F.U.Z.E. closure system?

F.U.Z.E. (Fluid Under Zero Entry) is O'Neill's proprietary chest zip system. Unlike a traditional back zip, the chest entry is positioned at the front of the suit, significantly reducing the zip seam running along the spine — a common source of cold water entry and heat loss in conventional wetsuits.

How does the Hammer compare to other O'Neill full suits?

The Hammer Series sits in the mid-range of O'Neill's lineup, above the Reactor 2 and below the Hyperfreak. It offers superior stretch, seam construction and closures compared to the Reactor 2, while providing excellent value relative to the premium Hyperfreak range.

Care & Maintenance

Rinse inside and out with fresh water after every session. Hang to dry inside out in the shade, away from direct sunlight. Do not tumble dry, bleach, iron or dry clean. Inspect the zip and closure system regularly. Store flat or on a wide hanger in a cool, dry place.
