Product Description

Designed by divers, the Thermal Fusion was rigorously tested by professionals to ensure the highest level of comfort and warmth.

Proven by science, independent laboratory tests by the Sport Innovation Centre (SPIN) validate the superior insulation value of the Thermal Fusion. Cold water immersion and controlled cold weather environmental tests determined effectiveness in protecting skin and core temperatures. Comparative testing against our competitor’s top rated undergarment confirms the Thermal Fusion superiority. The science proves that the Thermal Fusion performed best overall in preventing heat loss in extreme environments.

The Sport Innovation Centre (SPIN) collaborates with Olympic and Paralympics athletes, combining leading-edge technology, and applied research to address various team and individual needs at the highest level of training and competition. A key area of SPIN focus is on product testing and prototype development. Access to high performance Olympic athletes, as well as world-leading sports scientists, provides SPIN with the ability to establish and build connections between ideas generated from basic sport research, the athletic performance community, and the product development business. New textile and sensor technology developed through the SPIN Centre has positioned SPIN as a break-through leader in sport technology development throughout Canada, and around the world.

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 comfort cut thermal core constructed of Polar-Tec 200 fleece, delivers superior warmth. The second, outer layer, is a Polar-Tec Power Stretch Pro compression skin which streamlines the inner core to the divers body, provides a custom fit, and allows maximum range of motion.
