What is Wear Your Helmet to Work Day? Simple: It’s the one day of the year when we can share our passion with the rest of the world (or at least the office). Strike up a shock tuning conversation by the water cooler. Berate your cubemate because you can do a driver change in your endurance car quicker than he can move out of the way of your filing cabinet. Sleep in a meeting because your visor is tinted. You can even enjoy your safest commute of the year thanks to your trusty helmet. Working from home? Fold some laundry with extra head protection, and try not to scare your small children and pets too much.

The essential part of celebrating is what makes this event a marketing opportunity you won’t want to miss: Participants must share their festive headwear with the world under the hashtag #HelmetDay in order to win the day. At the end of the work day, we share our favorite photos with our audience and put our (helmeted) heads together to choose a winner to receive a band-new helmet from the sponsor.
