Fourth Element’s thermal protection has been tested in the World’s most extreme diving locations from the sub-zero waters of the Antarctic to the tropical temperatures of the Maldives and is used on expeditions where divers have never ventured before. The Fourth Element drysuit range includes the Arctic undersuit which is the choice of professional and recreational drysuit divers worldwide and the innovative biomapped HALO 3D.
HALO 3D – Drysuit Undergarments
The HALO 3D has body mapped insulation, strategically placed to enhance protection when in a horizontal trim. Designed for use underneath membrane and trilaminate suits, the HALO 3D is the perfect complement to our current range of drysuit thermal protection. In a layering combination with Xerotherm, HALO 3D is suitable for the harshest diving conditions on the planet. Accessory: Arctic socks
Arctic – Drysuit Undergarments
The Arctic’s two layers of high insulation, low bulk fabric, ensure exceptional levels of thermal protection. Constructed with comfort and utility in mind, the minimalist design provides outstanding performance under closer fitting neoprene drysuits. In a layering system, the Arctic is also suited for use underneath membrane and trilaminate suits. Accessory: Arctic socks.
Arctic Expedition Top – Drysuit Undergarment
The ARCTIC EXPEDITION brings knowledge of performance fabrics and biomapped design together to create a new undersuit in the EXPEDITION SERIES. Using strategically placed additional layers of high density fleece, wind and waterproof fabrics to protect critical areas of the body that experience greater exposure during the dive. The Biomapping technology maximises thermal protection whilst minimising bulk, allowing greater freedom of movement and comfort throughout the dive.
Xerotherm – Drysuit Undergarments
The Xerotherm is the ultimate Fourth Element base layer undersuit for drysuits. Made using Polartec® Powerstretch® which was originally developed for NASA, the Xerotherm traps a layer of air – a much better insulator than water – next to the skin, keeping the wearer drier and more comfortable.
The unisex range is designed to be worn under another undersuit or on its own under a neoprene drysuit and provides astonishing warmth without contributing to bulk or buoyancy. Accessory: Arctic socks
Xerotherm & X-core – Vests
The perfect addition to a diver’s thermal protection – get more warmth without significant bulking.
The X-core vest is described as the prefered alternative to electrically heated vests.
Both are worn as a base layer under any drysuit undergarments such as the HALO, Expedition or Arctic. There are no sleeves to bulk up around the arms and constrict movement. Accessory: Arctic socks.
Thermocline – Wetsuit Undergarments
The Thermocline neutrally buoyant system represents an evolution in thermal protection, using state of the art materials to maximise performance without compromising on comfort. The Thermocline neutrally buoyant wetsuit system comprises the long sleeved top and gives the equivalent protection to a 3mm wetsuit – but weighing less than 1kg (2.2 lbs). Thermocline also provides a real solution for people who suffer from neoprene allergies by eliminating contact between the skin and the wetsuit. Accessory: Fin socks
