This jacket has many advantages. It's comfortable, warm and looks good. However, the obvious disadvantages quickly overshadow the advantages. The jacket runs on a Dewalt battery and adapter (which is good, which is bad). The good thing is that there is always a charged battery ready to go. The bad news is that batteries wear out and damage bags. I've only had this jacket for a few months and there's already a hole in the pocket (see photo). I keep the jacket but I am not satisfied with the fragility.
