Description

The Women’s Xerotherm Long Sleeve Top is the ultimate thermal baselayer for female divers seeking superior warmth, moisture management, and comfort 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 every dive.

Designed to be worn beneath another undersuit or directly under a neoprene drysuit, the Xerotherm 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 a critical insulating air layer that enhances warmth and comfort even in demanding conditions.

The slim-fitting design sits close to the body for maximum thermal efficiency while remaining lightweight and low in buoyancy. Flatlock seams provide exceptional next-to-skin comfort, while the extended body length helps prevent separation between the top and leggings. Integrated thumb loops keep sleeves securely positioned during drysuit donning and can be removed before diving for optimal comfort.

Tested in extreme cold-water environments and trusted by professional organizations including the FBI Dive Teams, Norwegian Navy, and British Police Diving Units, the Women’s Xerotherm Long Sleeve Top offers proven performance for divers who demand reliable thermal protection in challenging conditions.
