Convert (almost) any bike helmet into a ski or snowboard helmet that holds your goggles in place! This particular model was built for my standard BERN bike helmet. This helmet is especially easy to convert to a snowboarding or skiing helmet because it already has a screw hole for a similar clip. Additionally, the BERN helmets allow you to take out the inner cushion (velcro). If your helmet does not already have a pilot hole in the back, you will need to drill on before screwing on the clip. WARNING: Be careful not to drill the pilot hole all the way through the helmet and especially be careful not to screw in a screw that is too long, as it will poke through to your head.
