I used @jake's solution, but it gave me trouble with the horizontal alignment.

My nav links are flex row, center aligned and his solution caused the element to shift upwards in order to stay horizontally center-aligned.

I fixed it by doing this:

a.nav_link-active {
  color: $e1-red;
  margin-top: 3.7rem;
}
a.nav_link-active:visited {
  color: $e1-red;
}
a.nav_link-active:after {
  content: '';
  margin-top: 3.3rem;      // margin and height should
  height: 0.4rem;          // add up to active link margin
  background: $e1-red;
  display: block;
}

This will maintain the horizontal alignment for you.
