Xerotherm LeggingsThe Fourth Element Xerotherm Leggings provide excellent thermal protection worn under another undersuit or on their own under a neoprene drysuit. Ultimate next to skin comfort is ensured by flat seams and the uniquely designed foot pockets guarantee that the garment stays in place during the dive. Separation of the top and leggings is prevented by the high waistband in which the long hem of the top can be securely tucked in.
