Since I have been so cold all winter I went for it and got a heated vest. I did a LOT of research and this is the one I settled on. Mostly because it has heat more heat pads in more places than most. I explain how I use it on my Reels. I am wearing a Large because it’s women’s sizing and the reviews said it ran small. I wanted a looser fit so I am very happy with the Large even though I’m a size 6. I literally throw my coat on over it and head out the door. If you are always cold, you will LOVE this! Get two battery packs so one is always charging. LTKSeasonal LTKfindsunder50 LTKstyletip
