A high performance diving undergarment, the Thermal Fusion maximizes warmth, while providing unrivalled flexibility and fit. At the heart of the Thermal Fusion is patent pending ThermalCORE technology. Inspired by the Whites Fusion dry suit, ThermalCORE technology is a unique, dual layer design. The first layer, a loose cut core constructed of Polartec Classic 200 fleece, fits a wide size range, and does not restrict movement. The second, outer layer is a Polartec Power Stretch Pro compression skin which streamlines the inner core to the diver’s body, provides a custom fit, and allows maximum range of motion.
 
 “The design criteria was clear”, says Justin Balaski, Brand Manager, Whites Manufacturing,” We set out to create an undergarment that would provide divers with excellent insulation value, unmatched flexibility, and a better than custom fit. The result is the Thermal Fusion”.
 
Designed by divers, the Thermal Fusion was subjected to rigorous testing by professionals to ensure the highest levels of comfort and warmth.  Proven by science, independent laboratory tests at the Canadian Sport Center were conducted to validate the superior insulation value of the Thermal Fusion.  Comparative cold water immersion and cold weather environmental tests were performed.
 
“Relative to the competitor’s undergarment, the Thermal Fusion protected the diver much more effectively..,” says Dr. Gordon Sleivert, VP of sport performance for the Canadian Sport Center Pacific, “the Thermal Fusion performed marvellously and prevented any drop in deep body core temperature...”

Patent pending Thermal Core Technology is a unique, dual layer design, that allows the diver an unlimited range of motion, with a streamlined fit.

The first layer, a loose cut thermal core constructed of Polartec 200 fleece, fits a wide size range and does not restrict mobility.

The second, outer layer, is a Polartec Power Stretch Pro compression skin which streamlines the inner core to the divers body, provides a custom fit, and allows maximum range of motion

The Polartec Power Stretch Pro compression skin, combined with Whites unique ATS (Air Transfer System) minimizes buoyancy, while allowing incredibly efficient air venting out of the suit.

Thermal Core Technology is at the heart of the thermal Fusion, resulting in an undergarment that is unmatched in flexibility, fit and warmth.
