The M2117 Pro is a men's fleece vest with six carbon fiber heating zones and a battery that runs up to 13 hours on the lowest setting. It tops out at 131°F, which is warm but below the hottest settings on some rival vests. The fleece build keeps it light and easy to move in, so it suits layering under a jacket or wearing on its own in cool weather. Owners rate it highly, though the heat output and battery life depend heavily on which setting you use.
