Fourth Element Thermocline Fin Socks

Fourth Element Thermocline Fin Socks

Fourth Element Thermocline is a lightweight, neoprene-free thermal system for scuba diving, snorkelling, freediving and warm-water surface sports. It is breathable, neutrally buoyant, machine washable and quick drying, with thermal performance comparable to a thin 2 mm neoprene layer.

The fin socks are thin lining socks for full-foot fins or neoprene boots. They help reduce rubbing and provide a comfortable barrier for divers who prefer a neoprene-free layer next to the skin.

Key benefits

• neoprene-free comfort for sensitive skin
• lightweight thermal protection with minimal buoyancy change
• breathable fabric that dries quickly between dives
• machine washable and easy to pack for travel
• made for layering or wearing as a stand-alone warm-water suit

Thermocline fabric behaves differently from neoprene: it may feel close-fitting when dry, then relax slightly in the water. A snug fit helps the garment stay in place and reduces water movement.
