CORE-X 6/4 Hooded Arc Zip Yamamoto

Luna ARC-Zip Wetsuit

Freedom where it matters. Zero restriction. Pure connection. The Luna ARC-Zip is one of those game-changing designs that lets comfort, freedom, and performance come together from your very first paddle-out.

ARC-Zip Entry System. Engineered for effortless movement, the ergonomic mini-zip follows a smooth arc across the chest, away from the shoulders. The result: no pulling, no pressure, no resistance—just almost weightless range of motion.

• Easy On, Easy Off: Significantly easier to enter and exit than traditional front-zip wetsuits, especially for surfers with tired or restricted shoulders. With the large entry hole, you can even slide in with both arms at once for fast, frustration-free changes.
• Zero-Flush Seal: Shoulder-to-shoulder closure locks in warmth and keeps cold water out.
• Unrestricted Movement: Fewer seams and lighter layers around the neck and shoulders boost paddling efficiency and upper-body mobility.

Tech Specs

Yamamoto #39
- Super Light Weight ECO friendly Non-Petroleum based Japanese limestone neoprene with the perfect balance between warmth, stretch and durability.
- Rubber made from the purest Japanese limestone.
- The limestone that YAMAMOTO use is sourced from Mt. Kurohime, which stores billion tons of the purest Japanese limestone. Out of such purest limestone, YAMAMOTO only uses the highest-grade limestone, containing 99.7% of calcium carbonate.

Nitrogen Gas Infused Closed Cell
The closed cells are packed together at an extremely high density and each individual cell is filled with nitrogen gas to prevent water penetration and increase heat retention. The nitrogen closed cell content is over 93% — over 30% higher than most competing materials — and with virtually no water absorption means the weight of this rubber remains nearly identical in wet or dry conditions, giving you more warmth than thicker wetsuits without the weight.

Honeycomb Structure
Yamamoto Corporation’s neoprene rubber is classified as (CR) “chloroprene rubber.” The special rubber incorporates an independent closed cell structure which adds high functionality including super light weight, high heat‐retention with good flexibility neoprene.
