Fourth Element Xerotherm Thermal Hat offers superb thermal
protection for a variety of outdoor activites from skiing and snowboarding,
rambling or just messing about on the boat.
The Fourth Element Xerotherm range of garments are constructed from
specialised Polartec® fabric, originally developed for NASA.
This specially developed fabric has a unique structure which provides
durability, versatility and complete freedom of movement. It is the fastest
wicking fabric in existence but is still proven to provide warmth even when
wet.
