Hidden under the lining of the Smart Coat is a slim and lightweight proprietary heating system. The system is not made with wires like traditional heating; the heat spreads through an inert specially-formulated polymer. The technology is safe, conducts heat uniformly and does not produce hotspots so there’s no risk of burning. It exhibits a positive temperature coefficient (PTC) which means there’s no need for thermostats or fuses. And the only wiring is a short cable that connects the battery to the coat.
The heat is concentrated in strategically placed panels on the lower back and on the front lower torso. The heat generated is ‘Far Infrared’ (FIR) and is the safest and healthiest heat on the spectrum. Instead of heating the skin, FIR is absorbed by the body to warm the muscles which improves circulation so you feel warm all over.
FIR is known to have many health-enhancing benefits including:
