The Thermal Fusion, a high performance diving undergarment, maximizes warmth and provides unrivaled flexibility and fit.
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 Center (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.
