An aero helmet with holes in it!

When Louis Garneau set about designing an aero helmet, they didn’t forget the most important thing –air. As in, the air has to move over your head to keep you cool so that you can actually continue to ride hard enough to take advantage of aerodynamics. The Course Helmet is the result. It’s no slouch in the wind tunnel, but much more importantly, it’s a very comfortable helmet to wear, even on long rides, and even in the middle of summer.
