Every diver has gone to outdoors shops looking for drysuit underwear or base layer and what most carry isn't great for diving because it still gives cold spots, doesn't have thumb loops or features that divers need when we're getting into and out of dry suits.
Fourth Element provides the Xerotherm ultimate base layer for use under a drysuit and is great when layered with Drybase and Sub Zero Jacket & Pants sets. Made using Polartec® Powerstretch® which was originally developed for NASA, the Xerotherm traps a layer of air
The unisex range is designed to be worn under another undersuit or on its own under a neoprene drysuit, it provides astonishing warmth without contributing to bulk or buoyancy.
