Think about the clothing that I mentioned here >>24813618 Now part of the clothing situation could also be coupled with a liquid inside the dual layered clothing that would heat up when introduced to the breath, and sorry for the crudeness, like they do in those sexual liquid enhancers that they advertise. This would give maybe even hours before hyperthermia sets in. This needs to be tested, as we have lost about 4 people at sea in just recent months. Did they drown, sharks, hyperthermia, starve, run out of energy, etc… We need to get to 100%.
