This is a ladies' fit Milwaukee heated puffer jacket in black, size Medium. It comes with full instructions, a charging station and a lithium battery pack which also incorporates a USB port for charging your phone or MP3 player, all tested and working. The jacket itself is made of quilted ripstop polyester (so pretty warm even without the heat function) and features a stand collar, front zip, front zipped pockets and a side zip pocket housing the battery connector cable and the battery itself when in use. There are three heat settings which are activated/deactivated by pressing a button on the chest, and the heat extends across the front, back, shoulders and down the sleeves. While it is labelled as suitable for 40"-42" chest, I would put it as more like 38"-40". The jacket stays warm for about 2.5 hours on the high setting, 3.8 hours on the medium and 7.6 hours on the low and so is excellent for the likes of watching an outdoor sport or any other occasion where the user is sitting or standing still in cold conditions. It looks to have had little or possibly no use and comes in its original Milwaukee box, but I have listed it as used just to be on the safe side. Checking the internet for prices of these, I see you would pay upwards of £200 for the whole bundle of jacket, charger and battery on the likes of Trade Counter Direct and so this will be a great bargain for someone. I will do my best to answer any questions.
