The jacket features three heating elements — two in the front and one in the back — that begin working within three seconds of activation, providing warmth, even as the mercury drops to unpleasant levels. Meltpartners Outdoors, the Chinese company behind the Heated jacket, claim that it has four different warmth settings, allowing the wearer to dial up temperatures that range from 77 degrees Fahrenheit (25 degrees Celsius) to 131 F (55 C) depending on individual comfort levels and current needs.
On the lowest of those settings, the integrated battery pack can maintain that level of heat for up to six hours before requiring a recharge. It isn’t immediately clear if that battery can be easily swapped out, allowing users to carry extras that would give them the option of extending their stay in the outdoors longer.
One of the advantages of having a heated jacket that is both windproof and waterproof is that it means you can cut down on the number of layers you need to wear underneath it. The Heated jacket should provide solid protection from the elements — the traditional role of an outer shell in a layering system — as well as plenty of warmth, which is usually generated by wearing an insulating layer such as a thick fleece or down jacket. In this case, outdoor athletes would only need to wear a base layer underneath the heated jacket to get the same level of comfort and warmth, at least in theory. If the jacket does work as advertised, it should allow skiers, snowshoers, fat bikers, and other winter athletes to move more quickly and efficiently.
