The Milwaukee M12 Grey Heated Hoodie Bare Unit is a heated garment made from 53% durable cotton with a 47% waffle-weave polyester lining. In autumn and spring the hoodie can be worn as a rugged outer layer. In winter, it is best as a base layer that allows to shed bulky undergarments while generating and holding heat close to the body. The battery offers 8 hours of uninterrupted running time, and powers multiple carbon fibre heating zones to core body areas. This heat can be adjusted to High, Medium, or Low. The garment is completely machine and dryer safe, and features an integrated cell phone pocket.
