The Fourth Element Xerotherm Beanie Hat is an excellent way to help stay warm before, between and after dives. The beanie is made using the same fast wicking and warm material as the rest of the Xerotherm range and features a soft fleece lining around the bottom for improved comfort.

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.
