Pro tip for anyone who has to be out in the cold and wants to stay as warm as possible.
Whatever your bottom layer is on your torso, put one of these at the top of the shirt collar (where your neck/back meet), and one at the bottom of your shirt where your spine and butt meet.
You have to be careful you don’t let them sit directly on your skin as are warm and the package cautions against burning. Ive never had that happen but let’s follow their warnings
Overall this does an amazing job keeping your spine and cortex warm; which overall goes a super long way to making your body feel warm.
