Milwaukee Tool M100U-21S Heated Jacket Small Navy Blue

Product Description

The MILWAUKEE TOOL M100U-21S is a men's heated jacket designed for tradespeople working in cold environments. Built from polyester with a zipper closure, it delivers battery-powered warmth across core zones, making it suitable for outdoor job sites, warehouses, and early-morning service calls. The jacket is sized Small with a 43-inch chest and includes five pockets for tool storage and accessory carry. At 4.65 pounds, it is substantial enough for cold-weather protection while remaining practical for active work. Licensed electricians, HVAC technicians, plumbers, and other field trades commonly rely on heated garments to maintain dexterity and core temperature during winter service work.

This jacket is suited for residential and light commercial field applications where extended outdoor exposure is part of the job. It fits tradespeople who need a wearable thermal layer that does not restrict movement on ladders, in crawlspaces, or during overhead work. The Small size and 43-inch chest measurement make it appropriate for slimmer builds or layering over a base layer rather than a heavy mid-layer. Five pockets provide dedicated storage for a phone, fasteners, or small hand tools while on the job.

Installation Notes

Heated jackets in this category are worn garments and do not require installation in the traditional trade sense, but battery connection and charging should follow the manufacturer guidelines for the compatible battery pack. Inspect the heating elements and wiring harness before each use for signs of damage. Do not machine wash without confirming care instructions from the manufacturer, as heat elements can be damaged by improper laundering. Store the jacket with the battery removed when not in use for extended periods.
