Today, my touring pal and I were on a long ride preparing for our upcoming tour. In a freakish accident he slipped and cut his ankle on the pedal. It was so unexpected. I had packed some basic first aid supplies and was actually riding today with my panniers and bike loaded as I anticipate it loaded on the tour. As we tried to stop the bleeding which was more than just a casual cut, we pieced together a "bandaid" with a microfiber cloth and gorilla take. It held until he got to the emergency room. Luckily it was only a few stitches and didn't do much damage.
That got me thinking about what first aid items I really need on a tour. I felt very unprepared. So, what do you take for emergency first aid with you on a tour?
