What Not to Wear: Black. Even if it has reflective elements. Those little silver strips will only prevent walkers from crashing into you. And only if they are wearing a headlamp that makes those elements reflect. Car drivers, bicyclists and even other runners will not see you. So, unless you're a running ninja...
My two favorite items:
- Marmut headlamp - bright light lets me see the path, avoiding cracks and twisted ankles, and be seen. Comfortable enough for mid-distance runs, but I prefer to wear a beanie under it for long-distance comfort.
- Amphipod arm band - multiple LEDs can be seen from at least 30 feet and it fits snug around my arm thanks to Velcro. I like to wear it wrapped around the arm that is facing street side for maximum visibility.
