Alpha
Heat Vest:- is powered by a rechargeable battery, commonly
integrated right into a discreet pocket of the vest. The battery
ability guarantees several hours of heat, depending on the chosen
warmth stage. Most variations of the Alpha
Heat Vest can provide up to eight hours of heating on the lowest
setting and shorter durations on higher settings. The battery is
rechargeable, and many fashions are well suited with energy banks for
longer outings.
