The Milwaukee M100U-21L is a heated work jacket built on the M12 battery platform. It has three heat zones (chest, back and pockets) with independent high, medium and low settings, and Milwaukee rates run time at up to 12 hours on low, 6 on medium and 3 on high. The shell is a stretch polyester with wind and water resistance and a DWR finish, plus roughly three times the insulation of a standard jacket. It suits tradespeople and outdoor workers who already own M12 batteries; against generic heated jackets, the zone control and battery pass-through are the main advantages, while the bulk and the need to manage a battery are the trade-offs.

Owners of Milwaukee heated gear generally rate the heat output and zone control highly and treat it as a serious work jacket rather than a fashion piece. Complaints center on battery weight and on heat fading toward the end of a charge.
The Milwaukee M100U-21L is a men's heated work jacket with Hexon Heat Technology. It has three heat zones: chest, back and pockets. Each zone has high, medium and low heat settings. The zones can be controlled as chest and back, pockets, or both.
The jacket is made from 100% stretch polyester fabric with 3X more insulation. It is wind and water resistant with a DWR finish. An adjustable waist drawcord and cuffs help keep heat in. It is washer and dryer safe.
It has 5 pockets: 2 zippered hand pockets, 1 interior zippered pocket, 1 exterior zippered pocket and 1 zippered battery pass-thru pocket. The pass-thru pocket lets you place the battery at the front or back. The jacket runs on M12 batteries and ships as a kit with a battery and charger.
