Men’s Xerotherm Top
£135.00
The Fourth Element Men’s Xerotherm Long Sleeve Top is a high-performance thermal baselayer designed for drysuit diving. Made with Polartec® Powerstretch® fabric, it delivers exceptional warmth, rapid moisture wicking, low bulk, and all-day comfort while maintaining thermal performance even when wet.
Description
The Men’s Xerotherm Long Sleeve Top is the ultimate thermal baselayer for divers seeking maximum warmth, comfort, and moisture management beneath a drysuit. Constructed using genuine Polartec® Powerstretch® fabric originally developed for NASA, this advanced thermal layer traps a protective layer of insulating air next to the skin, helping divers stay warmer, drier, and more comfortable throughout the dive.
Designed for use beneath another undersuit or worn directly under a neoprene drysuit, the Xerotherm Long Sleeve Top delivers the fastest moisture-wicking performance in the Fourth Element range. Moisture is rapidly transported away from the skin through fine fibres and dispersed across the fabric surface, helping maintain an insulating air layer even in challenging diving conditions.
The slim-fitting design sits close to the body for optimal thermal efficiency. Flatlock seams minimize chafing and pressure points, while the extended body length helps prevent separation between the top and leggings. Integrated thumb loops keep sleeves securely positioned when donning a drysuit and can be easily removed from the thumbs before diving.
Trusted by professional dive teams including the FBI Dive Teams, Norwegian Navy, and British Police Diving Units, the Xerotherm Long Sleeve Top provides exceptional thermal performance with minimal bulk and buoyancy, making it a proven choice for cold-water divers around the world.
