Heated gloves that can be used with heated jackets from Milwaukee Bosch, DeWalt, Metabo... Also the capacity of their battery and how small it is is a big benefit to replacing the power adapter that comes with the jacket. I think I might get the battery pack myself because it's so small and has great output, and is very small. I would even put a second pack inside the battery pocket as a spare, they are so small.   -   Link to the website you can purchase from:
