Fourth Element, a diving equipment and thermal protection specialist, has introduced an improved version of its Arctic Undersuit range. The redesigned suit, focusing on comfort, utility, and environmental responsibility, aims to surpass its predecessor, setting a new standard in thermal protection for divers.

As part of Fourth Element's dedication to OceanPositive sustainability, the updated Arctic Undersuit incorporates 80% recycled polyester in the outer layer and 100% recycled polyester in the inner layer, delivering enhanced performance while prioritizing the planet.

Crafted with comfort and utility in mind, the minimalist design of the Arctic Undersuit makes it a versatile piece suitable for use under various drysuit types, including neoprene, membrane, and tri-laminate. Utilizing high-insulation, low-bulk fabrics, the suit creates a micro-climate around the diver, ensuring dryness and warmth. The high-density inner fleece provides superior insulation and moisture-wicking, while the outer layer with a resin coating enhances durability and maintains a snug fit.

The Arctic Undersuit's effective management of air within the fibers reduces the need for excessive loft, minimizing air movement and preventing cooling without trapping air. Even when wet, the suit retains significant thermal performance, offering comfort in real-world diving conditions, as reported by divers who completed dives in relative comfort after drysuit failures.

Backed by extensive field testing from entities like the Norwegian Navy, the British Antarctic Survey Dive Team, the French Marines, and the Danish Navy, the Arctic Undersuit utilizes high-technology fabrics and has been tested from the Arctic to the Antarctic, ensuring reliability and performance.
