These lightweight devices fit comfortably and could save a life if someone breaks through the ice. A warm, insulated and buoyant suit can also protect a person. A sudden breakthrough into freezing water could shock a person into not thinking clear. A flotation device could keep the person’s head above water even if that person panics.
