Lunasurf Core-X ARC-Zip Wetsuit: Built to Surf Longer in Cold Water

Introducing A New Standard in Cold-Water Performance

Lunasurf Core-X ARC-Zip Wetsuit: Surf Freer, Move Easier, Stay Warmer 

Every surfer knows the frustration: tight shoulders, a pulling chest, or a wetsuit that leaves you stiff and exhausted halfway through your session. The Lunasurf Core-X ARC-Zip wetsuit changes all that. Designed for maximum freedom of movement, it lets you pop up, turn, and flow through every wave with effortless ease. Less restriction across the shoulders and chest means you stay loose, move naturally, and surf longer—without compromising warmth or comfort. From your first wave to the last, this wetsuit feels like it was made to move with you, not against you.

At Lunasurf, we believe the best wetsuit is the one you forget you’re wearing. Light. Warm. Unrestricted. Built to move exactly as your body moves in the water.

The new Lunasurf Core-X ARC-Zip wetsuit is the result of that belief—our most advanced cold-water wetsuit to date, designed from the ground up to eliminate restriction, reduce fatigue, and keep you warmer for longer sessions.

Available in 4/4, 5/4, and 6/4 thicknesses, the Core-X ARC-Zip is engineered to handle everything from cool mornings to full winter conditions—without sacrificing flexibility or feel.

Rethinking the Wetsuit Entry System

Progress in wetsuits usually comes from small, meaningful changes. The ARC-Zip is one of them—refining what works, removing what doesn’t, and noticeably improving how a wetsuit feels in the water.

Freedom Where You Need It Most

Most wetsuits focus on warmth or style—but few consider how a wetsuit feels when you actually move. The ARC-Zip entry system was designed to put freedom first.

Instead of a straight zipper pulling across the shoulders, the ARC-Zip follows a smooth, ergonomic arc that sits away from high-movement zones. The result? No shoulder pull, no chest restriction, and no neck pressure—just pure, unrestricted movement.

You’ll feel it from the very first paddle: lighter, looser, and more natural. This means longer sessions with less fatigue, letting you enjoy every wave to the fullest.

The zip feels light, low-profile, and almost invisible—more like wearing a necklace than a wetsuit closure.

Easy Entry. Better Seal.

The ARC-Zip isn’t just about freedom—it’s about usability and warmth.

Easy On, Easy Off

More flexible than a chest zip and as simple as a back zip, the ARC-Zip making entry and exit fast and frustration-free—even after long sessions, is especially appreciated by surfers with tired or limited shoulder mobility.

Zero-Flush Seal

Unlike traditional chest zips, the ARC-Zip seals completely across the shoulders, locking warmth in and preventing cold-water flushing.

Unrestricted Movement = Better Surfing & For Longer

By minimizing seams and reducing layering around the neck and shoulders, the Core-X ARC-Zip dramatically improves upper-body mobility.

You’ll feel:

• Increased paddling efficiency

• No shoulder bind or tightness

• No choking or pressure around the neck

• A lightweight, low-profile fit

You paddle longer. You stay looser. You surf better.

Anatomically Engineered Fit

Every Core-X ARC-Zip wetsuit is built using 3D anatomical body paneling, designed to mirror natural human movement. Each panel works with your body, not against it, creating a second-skin feel that stays comfortable in and out of the water.

This precision fit delivers:

• Exceptional flexibility

• Consistent warmth

• A direct, connected feel to the ocean

Warmth Without Bulk

Constructed entirely from 100% premium YAMAMOTO limestone neoprene, the Core-X ARC-Zip offers industry-leading warmth, softness, and stretch—without unnecessary thickness or weight.

Smart panel placement and minimal layering retain heat efficiently while maintaining maximum flexibility and board feel.

Available Thicknesses

• 4/4 – Ideal for cool to cold conditions where flexibility still matters

• 5/4 – Extra insulation for colder water and longer sessions

• 6/4 – Maximum warmth for serious winter surfing

No matter the thickness, the ARC-Zip ensures freedom of movement remains uncompromised.

Performance-Driven. Responsibly Made.

The Core-X ARC-Zip is built for high-performance surfing with sustainability at its core:

• 100% YAMAMOTO limestone neoprene

• Eco-friendly construction using food-grade canola oil instead of petroleum

• Manufactured with renewable energy and recycled fabrics

• Long-lasting, ocean-safe materials

• Latex-free, hypoallergenic, and skin-friendly

High performance. Minimal impact. Maximum freedom.
