Hypothermia occurs when the body’s temperature drops below normal, specifically when the core temperature drops below 35 degrees Celsius (95° F). As the temperature drops, there is a gradual reduction in muscle coordination and movement.
Consciousness is reduced and a loss of consciousness can occur when the body’s core temperature drops to approx. 30-32 degrees Celsius (86-90° F).
How immersion suits work
The insulation in an immersion suit works by locking air and radiant body heat in the suit. The better the insulation, the higher the immersed CLO value. This is important as higher immersed CLO values indicate more efficient heat maintenance, which helps prevent hypothermia and can extend survival time in the water.
All VIKING suits are specially designed to maximize protection against hypothermia.
VIKING SOLAS immersion suits have a minimum immersed CLO value of 0.75 with a documented protection level of 6 hours in 0° cold water. Some of our suits have higher immersed CLO values, providing even greater protection.
