Milwaukee M12 Heated TOUGHSHELL Jacket Kit M100U-21S

MAXIMIZING THERMAL ENDURANCE WITH HEXON HEAT TECHNOLOGY

The M12™ Heated TOUGHSHELL™ Jacket represents a significant mechanical leap in jobsite apparel, moving beyond standard heating elements to the advanced HEXON Heat Technology. This system is engineered for the professional who demands rapid thermal recovery and consistent heat distribution across the chest, back, and pockets. By integrating 3X more insulation than previous generations, the jacket maintains a higher thermal equilibrium, ensuring that even when the M12™ REDLITHIUM™ system is cycled down, heat retention remains optimal. The TOUGHSHELL™ stretch polyester is not just about mobility; it is a high-denier barrier equipped with a DWR finish to withstand the abrasive environments of a modern jobsite while shedding moisture and wind.

• / HEXON Heat Technology delivers the industry's fastest heat-up time with expanded coverage across primary core zones.
• / TOUGHSHELL™ 100% stretch polyester provides 5X longer life than previous softshell materials while maintaining full range of motion.
• / Versatile battery pass-thru pocket allows for front or back placement, optimizing comfort whether sitting in a vehicle or working overhead.
