Yes, One Stop Knife Shop has them available at http://www.onestopknifeshop.com/store/550.html. At the bottom you will find differing lengths of red, yellow, black, or a combination of the three all with silver reflective threads.

Be aware however, that I have not ordered or tried this parachute cord yet myself. They are listed as “commercial” grade parachute cord instead of “military” grade, but they still are listed as having seven internal strands. I am unaware how their quality compares to “military” grade parachute cord.
