The Fourth Element Thermocline Long Sleeve Top can be worn on its own as a thermal top or with a pair of Thermocline leggings or shorts as a lightweight shortie. Alternatively, layer this underneath a neoprene wetsuit to increase thermal protection of the body core by the equivalent of an extra 2mm of neoprene, without affecting your buoyancy.
PLEASE NOTE: Due to initial stock availability and demand some Thermocline 2 garments and sizes have a longer delivery time. It is expected that a stable supply will available from the second week of July. In the meantime we will notify you of any unforeseen supply issues when you order.
Thermocline garments are much more versatile than neoprene as it can be worn comfortably before, during, between and after dives as well as during surface water sports. When on the surface the inner fleece layer draws moisture away from the skin and wicks through the breathable membrane where it evaporates off the nylon surface. Once in the water, the membrane traps a thin layer of water next to the skin and prevents colder water flowing over the body.
Thermocline garments are much easier to care for compared to neoporene. The material can easily be washed in a machine and can be rolled, folded or just stuffed in your bag with risk of damaging the material unlike neoprene which is crushed if folded. The 2018 Thermocline material has also been updated to include recycled nylon that mostly comes from 'Ghost Nets' pulled from our seas.
Made from 33% Econyl® Recycled Nylon / 57% Polyester / 10% Elastane. Machine Wash at 30°C
