Keep an eye on what's behind you without continual head checks.

Attach the Pro Helmet Third Eye® Mirror to your smooth hardshell or Styrofoam helmet and you'll know what's behind you without taking your eyes off the road ahead. The shatterproof aluminized glass mirror won't discolor. Mounts on either side of your helmet. This is a great tool for keeping track of slower riders in your peloton.
