The protection provided against the initial responses to cold water immersion by a partial coverage wet suit was assessed. Eighteen subjects performed three 2-min immersions into water at 5°C. During each immersion, the subjects wore either: a) cotton overall, b) trunk and arms 'wet' immersion suit, or c) 'dry' immersion suit. Results showed that the dry suit provided significantly (p < 0.05) greater protection against the initial cardiac and ventilatory responses to immersion than either the wet suit or cotton overall assemblies. The responses recorded in the wet suit were similar to, and in some cases did not differ from, the cotton overall. We conclude that immersion suit design and tests should consider all of the responses associated with accidental cold water immersion and not just those resulting in a fall in core temperature.
