The Fourth Element Men’s Xerotherm Long Sleeve Top is the ultimate base layer for drysuit divers, offering unparalleled thermal performance and moisture management. Made using Polartec® Powerstretch®, a fabric originally developed for NASA, the Xerotherm traps a layer of air next to the skin—a far better insulator than water—keeping you significantly drier and more comfortable throughout your dive. Its unique knit structure provides the fastest wicking action in the Fourth Element range, efficiently drawing perspiration away from the skin and spreading it over the outer surface for evaporation. This top performs exceptionally even if it gets wet. Designed with flat seams for next-to-skin comfort, a long body to ensure overlap with leggings, and thumb loops to keep sleeves in place during donning, it's perfect for technical diving, cave exploration, and any cold-water activity where staying warm and dry is critical. Its low bulk and lightweight nature mean it won't compromise your trim or add unnecessary buoyancy.
