Fourth Element Xerotherm Men’s Vest
The Fourth Element Xerotherm Men’s Vest is the ideal addition to any diver’s thermal protection system. Designed to boost core warmth without adding bulk or affecting buoyancy, this vest allows for maximum freedom of movement thanks to its sleeveless design. It is perfect for divers who want enhanced warmth without compromising mobility.
As part of the Xerotherm range, this vest is made using Polartec® Powerstretch®, a material originally developed for NASA. The fabric traps a layer of air—far superior to water as an insulator—next to the skin, keeping divers drier and more comfortable. The Xerotherm can be worn on its own under a neoprene drysuit or layered beneath another undersuit for added warmth.
What sets the Xerotherm apart is its exceptional moisture-wicking ability. The fabric’s knit structure pulls moisture away from the skin along fine fibers, spreading it over the outer surface to maintain a thin insulating layer of air. This feature is so effective that some divers have reported being unaware of minor suit leaks until after the dive.
Renowned underwater filmmaker Doug Allan praised the Xerotherm after testing it in -2°C (29°F) waters within the Arctic Circle while filming for the BBC’s The Blue Planet. His verdict: “The performance is superb.” The Xerotherm Men’s Vest offers unparalleled warmth and comfort, making it an essential piece of thermal gear for divers facing cold-water conditions.
