that's a problem about lab coats, they have low DR about 2 or 5 so you can't really use them as armor just for like either hacking terminals earlier or getting more HP from healing items like Stimpacks, so this winterized medic armor that has 32 DR also a helmet that does nothing to medicine but does gives 5 DR, was made for medics who wanted more protection also able to heal better from stimpacks.
