Thermocline is probably the most versatile thermal protection system for use in extreme watersports. Breathable, comfortable and lightweight, the garments are also fast drying with the equivalent thermal performance of 2.5mm neoprene.

Made using Polartec® Aqua Shell® fabric, the garments are also neutrally buoyant and machine washable. The Thermocline system can be used as a lightweight wetsuit for snorkelling, pool training suit or as an effective additional thermal layer underneath a wetsuit or semi dry.

Loss of heat from the body can result in poor decisions, can lead to exhaustion and speed the onset of hypothermia

State of the art breatheable, waterproof, flexible and warm fabric developed by climate control specialists, Polartec® has been used by fourth element to create the Thermocline range, which has been tested in some of the most extreme diving conditions in the world.

The Thermocline is made from Polartec® Aqua Shell® fabric and has a thermal performance equivalent to that of 2.5mm of neoprene whilst being neutrally buoyant. Worn on its own or underneath a wetsuit or drysuit for additional thermal protection, the Fourth Element Thermocline system represents and evolutionary step in diving thermal protection.

The fabric is fleece-lined - it is comfortable and warm against the skin. Four way strech gives complete freedom of movement. A breathable membrane means that the Thermocline can be worn all day.
