Milwaukee 255B-21XL M-12 heated Axis Layering System
This is a well thought out and built cold weather protection system. The inside layer zipper doubles as a zipper that also zips into the outside shell of the second layer. It snaps into the outer shell in three places, as well. It snaps to the outer layer behind the neck, and at the end of both sleeves. The wrists of the inner liner have elastic preventing any cold air from entering through and under the the inside liner of the arms at the wrist. I’ve used the jacket once so far, and the battery lasted about 7 1/2 hours on low, (switched to medium and high for a few minutes during that time). It generated plenty of heat on a 28 degree morning with about a 5 m.p.h. wind. It was comfortable in that temperature without even having to power on the heating element. I Haven’t owned this system for long, but if the heating element and wires are as good of quality that the outside components appear to be, it should last for 5 years + if not abused.
