What brand is your heated vest? I have been leaning towards getting one. Any negatives with it? Seems like a great idea. I also am a big fan of wool. Another trick is the heater body suit and throw a few hot hands in the bottom, with my feet. It’s super toasty on cold days.
Before you buy one, read the reviews. They don't work with all phone power packs. I have one, made by Doace, that works fine with my 20k mAh pack but won't even start with my wife's 10k pack. I don't know what the difference is. They both have the same USB plugs and the same voltage. Some vest makers have a list of packs that are known to work.
