If somebody got trapped in ice after an avalanche they probably be affected by hypothermia... this jacket or sweater helps the victim by heating their body to an optimum temperature so hypothermia doesn't set in. Probably if anybody wants to make this jacket will require mini coils and batteries (rechargable ones).

Reward: just tell me this idea is already present or not

well that is an "amazing" idea, well the next time i wear a sweater i will remember to put in a pair of coils, rechargeable bateries and a recharger inside it instead of wearing a water proof inflatable jacket with a layer of insulation which will also help me float.

anyways when i go for a dip in sub zero water i will remember to wear a sweater.
