The extra large Realtree camo heated QUIETSHELL jacket kit is powered by the M12 REDLITHIUM battery. Each heated jacket uses carbon fiber heating elements to create and distribute heat to the chest, back and front hand pockets. A single touch LED controller heats up the battery heated jacket to three heat settings. The MILWAUKEE heated jacket kit's Quick-Heat funtion heats up three times faster than previous jackets and market competitors. The heated hunting jacket also features Realtree Edge camo pattern. The QUIETSHELL stretch polyester material reduces noise from movement and provides wind and water resistance. This kit comes with one heated jacket, an M12 battery and compact charger and power source.
