Fourth Element Xenos ARC Wetsuits 2025: The OceanPositive Revolution

Now Available for Pre-Order at Mike’s Dive Store - Expected Delivery January 2026

The next generation of sustainable dive wear is here.
Built for warmth, performance, and a lighter footprint, the all-new Fourth Element Xenos ARC redefines what a wetsuit can be - combining exceptional thermal protection with cutting-edge eco innovation. Designed for comfort across multiple dives, it’s the perfect blend of OceanPositive design, natural materials, and uncompromising performance.

Built for cooler waters and multi-dive days, the Xenos ARC 7mm delivers top-tier warmth, comfort, and eco innovation in one outstanding wetsuit. Designed for effortless donning even when wet, its fast-dry linings and ultra-stretch recycled fabrics make it easy to slip in and out of, while offering complete freedom of movement underwater.

Made using Ocena®, a blend of natural rubber and recycled car tyres, this wetsuit achieves a perfect balance between warmth, flexibility, and environmental responsibility. With 85% natural rubber and GRS-certified recycled linings, it’s a serious step forward in sustainable dive gear.

Featuring a double wrist seal system for glove integration, internal silicone ankle seals, and a Glideskin neck seal, it keeps cold water out and warmth locked in. The Thermoflex torso lining adds extra insulation where you need it most, while the triple-glued, blind-stitched seams ensure long-lasting durability and comfort.

Features:

Ocena® construction – 82% bio-based content with recycled tyres for compression resistance
Recycled linings for ultimate stretch and recovery
Thermoflex torso lining for core warmth
Double wrist seal for easy glove integration
Internal silicone ankle seals and Glideskin neck seal for maximum water protection
Triple-glued and blind-stitched seams for watertight strength
Smoothskin zipper pad and abrasion-resistant knee pads
Fast-dry, low-friction linings in arms and legs
Cut-away heel notch for easy donning and doffing

Warmth, comfort, and eco innovation come together in the Xenos ARC 7mm. Designed for serious cold-water divers who care about the planet, it performs brilliantly while keeping environmental impact to a minimum. You’ll stay warmer, dive longer, and feel good doing it.

Pro Tips for Easier Donning & Longer-Lasting Seals:

Add Mcnett Neoslix to help with donning and doffing your wetsuit while also prolonging the life of the seals, or try the Waterproof Donning Socks. These Lycra socks are designed to make getting into your wetsuit effortless, protecting the suit from wear and tear and preventing you from getting stuck. They also provide comfort for barefoot fin users, helping to prevent painful rashes with a soft, protective layer.
