The Fourth Element Arctic X Socks are thermal diving socks built for cold-water drysuit diving. A dual-layer recycled construction with a fleece inner layer and DWR-coated outer layer delivers warmth without bulk. The inner liner separates to speed drying between dives, making it a practical addition to any cold-water diving setup.

Features & Fitting

Made with recycled materials: Outer shell, inner shell, and lining all use recycled fibres. Main fabric carries Oeko-Tex 100 and Bluesign certification; lining holds GRS, Oeko-Tex 100, and Bluesign certification. Plastic-free packaging.
Dual-layer construction: Separate inner and outer layers work together for warmth and moisture management. The inner liner can be separated from the outer layer to speed up drying between dives.
Fleece inner layer: Soft fleece retains heat directly against the foot throughout the dive.
DWR-coated outer layer: Durable Water Repellent coating causes water to bead off the surface, keeping the socks dry between dives and during surface intervals.
4-way stretch fabric: Moves with the foot in all directions for a snug fit without restricting movement or circulation.
High performance low bulk: Provides thermal protection without adding volume inside a drysuit boot.
Reflective prints: Subtle reflective detailing for visibility in low-light conditions.
Machine washable: Can be washed at home without specialist care.

Materials with purpose

Ocena Natural Rubber

OCENA® is a natural rubber developed by SHEICO Group for use in and around water. It replaces petroleum-based neoprene in wetsuits and other marine gear, cutting the carbon footprint by up to 95%. OCENA® carries USDA certification with 82% bio-based content, and SHEICO holds FSC Chain-of-Custody certification, so the rubber is traced through a responsibly managed supply chain.

ECONYL®

ECONYL® is 100% regenerated nylon, a significant percentage of which comes from fishing nets recovered from the sea..

UPF 50+

Rashguards The UPF 50+ fabric is a blend of recycled nylon and xtra life™ LYCRA®, which gives generous stretch and also offers extended protection against chlorine and salt.

No More Microplastics

Water soluble | Recyclable | Compostable
Biodegradable | Non-toxic | Marine-safe
Zero waste

Our No More Microplastics packaging is 100% water soluble, recyclable, compostable and biodegradable – eliminating the problems that plastic usually causes when we attempt to dispose of it.

A Better Neoprene

Limestone Neoprene | Recycled Rubber | Dope-Dyed Yarn (exclusive products)

After the neoprene creation process, the redundant trimmed materials will be recycled and reused in the mixing process to produce more neoprene sheets. Overall huge amounts of raw materials are saved, energy consumption is reduced and waste water and air emissions are minimised during production.

Recycled materials

The recycled dive fin. It is the unique combination of materials which makes this fin special. The plastic is made from 100% reclaimed post-consumer waste polypropylene and the rubber is made with recycled TPR. By using materials in this way, we are preventing plastic being sent to landfill or ending up as waste in the ocean as part of fourth element’s mission to become OceanPositive.
