The updated Fourth Element Xerotherm Socks offer excellent thermal protection and comfort and are thin enough to be worn under other drysuit socks yet capable enough of thermal protection in their own right. They are comfortable thanks to the flat-locked seams and fast-wicking fabric.

Xerotherm is made using Polartec® Powerstretch® which was originally developed for NASA and effectively traps a layer of air - a much better insulator than water - next to the skin, keeping the wearer drier and more comfortable.

The knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the fourth element product range. Moisture is drawn out through the fabric along fine fibres and then spreads out over the outer surface. This maintains a thin layer of air next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive.
